A lot of thought goes into buying Used Fork Trucks. The seller might con you and sell you something that would work whilst being sold, but would go bust within two days of purchase. When you take the same thing and trash it in front of the seller, he comes up with a decoy story saying that it would definitely have been your fault and would easily wash his hands off the whole thing. A used fork truck has to be bought with a lot of caution. First you need to be technically aware of all the parts in it and its functionalities. Secondly, its condition should be good and you ought to get it verified by a professional. The final thing would be that you need to make the purchase from a trusted dealer.

A purchase from a trusted dealer would ensure you end up with the right purchase. When you approach a trusted dealer, you are at least assured about one thing and that would be the legitimacy about the product. This is one of the most important facts about the fork truck. An official dealer can never ever think of selling you a defunct or non operational truck because he knows it very well that he can be sued anytime. He would dare not do anything of that sort. If something like that happens, then he would be inviting a lawsuit against him on the grounds of selling illegal and defunct consumer goods and might end up coughing out a huge compensation.

The dealer takes care of the rest of the factors involved. The machine has to be done well. It is taken care of by the dealer. The machine gets oiled and lubricated well. It is taken care of by the dealer. The machine is sold with a certain warranty period. It is again taken care of by the dealer. The warranty stamp ensures that the buyer can approach the seller anytime within that period in case an anomaly arises out of the machine. The seller will be entitled to sort out that anomaly and ensure that the machine starts working all over again.

These are certain benefits that come when you make the purchase from a trusted dealer. The machine goes nowhere, the money goes nowhere. Everything remains then and there and stays under the guidance of the dealer.

Motors are the basis of most electronic machines these days. One of the most commonly used motors is the DC engine,which offer high speeds and torque for the machines. It does so by taking the electrical energy from the mains and converting it into mechanical energy. This, in turn, is used for position maintenance and motion control.

The working of the DC motor is based on a strong magnetic field created by an electromagnet. It synchronizes this magnet with the armature wound and offers speed and power to control systems or maintain a position. This motor has two variations, namely brushed and brushless. This article will delve further into the working of the latter. First, let’s learn about the challenges posed by brushed motors, which have been overcome by brushless ones.

Challenges of Brushed Motors

The main problem of these motors is that the brushes usually wear out with time. Since these brushes are constantly making and breaking connections, there is a possibility of sparks and, as a result, short circuits. These may harm the machines. Brushed custom motors are known to limit the speed and not allow the machine to reach its maximum potential. They also limit the number of poles on the armature. Lastly, with the electromagnet in the center, they maymake it difficult to cool the motor quickly.

Working of Brushless Motors

Brushless DC motors (BLDC motors) areessentially brushed motors turned inside out, without the brushes. All you need are permanent magnets on the rotors and electric ones on the stators. Then you can easily connect the motor with a computer using high-powered transistors.

Benefits of BLDC

Since there are no brushes and they work with computer controls, BLDC motors are more accurate. This has earned them the nickname of precision motors. They can adapt to various speeds with the same amount of efficiency. The absence of brushes also means no sparks and no stoppage due to wearing out of brushes. As a result, the motors work longer and faster. Also, since the magnet is placed outside, cooling them naturally or with automated fans is easy.

From electrical vehicles in transport to domestic and commercial HVAC systems, from industrial engineering needs to motion control spaces, these motors are ubiquitous in manufacturing units across the world.

The history of Momo Corse wheels and other car accessories goes back to 1960 when Giampiero Moretti, a student of politics at the University of Pavia, Italy and an amateur racing driver, got a friend to make a very special steering-wheel for his racing car. The wheels were smaller than the one that is normally used, but with a very large handgrip. This gave a much better hold and made the car easier to handle and drive.

It took little time for this odd steering wheel to attract the attention of many racing drivers including the English driver John Surtees of Ferrari. He tried it and had it mounted on his single-seat Formula One race car and eventually won the F1 championship that year. A production plant in Tregnago, near Verona, Italy, was opened in 1969 to produce these steering-wheels. The company took the name Momo, a derivative from the initials of Moretti and Monza.

Initially sales of the steering wheels by Momo were limited to the racing world. From 1970 it began to widen its horizons by diversifying its production and broadening its steering-wheel range. It began to produce light-alloy road wheels, a product to which Momo brought new concepts in design, look and marketing. For four years between 1986 and 1990 the product range was extended, particularly in the wheel sector that continued to be a pulling force.

In the mean time Momo’s diversification strategy went on and devised out ventures into new car accessories. Consequently, Momo Corse was created in 1993 to design and produce hi-tech racing car accessories and also to import the best of the world’s racing fitting wares. Since then it became a class by itself and won the confidence of millions of car owners all over the globe. Thus, what was started as a passion grew into a big business thanks to gorgeous designing, use of innovative and advanced technology, ensuring safety, and taking care of quality.

You may be surprised to learn just how much financial power rests in the hands of the person who answers the phone at your auto repair shop. As a shop owner, you put a lot of time into getting that phone to ring. The first phone call from a potential customer is your best chance to make a good impression. How is your business first represented to your potential patrons?

Customers needing auto repair have a sense of urgency when they make the call to your auto shop. Transportation is both a necessity and an investment; when they call your business for service, they want to know that their vehicles will be in capable hands. How is that first communicated to your potential clients? If your answering system involves an answering machine or an uninformed receptionist, you may be losing calls and clients by the day.

You may be the best shop with the most skilled mechanics in your local area, but if that is not communicated to your clients on the initial phone call, your business will suffer. The average auto repair ticket is approximately $300. If your phone answering system causes you to lose one call per day, and you are open 5 days per week, your business loses $1500 per week! This adds up to $78,000 annually!

Having a pre-determined script for any type of call that may come into your shop is an ideal way to assure that your receptionist handles inquires in a manner that will convert the call to sales, says Gerry Frank and Keith McCrone, co-owners of Automotive Profit Pro. When this is executed properly, 75% of calls can be converted into appointments.

Customers typically call auto shops for three main reasons:
1.They have a question or problem. This customer usually calls asking if you can fix their air conditioner or if you work on specific types of cars, such as, Do you work on Hondas? They want to know that you can confidently take care of whatever problem or vehicle that they may have.
2.Calling to schedule an appointment. This may be a current customer or a new prospect and they may be calling for either routine service or an emergency. It is important to determine all of the variables of the caller and help them accordingly.
3.To get an estimate. This person is usually labeled as the price shopper. Dont underestimate this caller; more often than not this customer is looking to establish a relationship with you and your auto repair shop.

Each of these phone calls is an opportunity to set an appointment and clinch the sale. Building a relationship with your potential clients as their auto care professional is established through their ability to trust you with their auto maintenance needs.

The costs of running a car are increasing all the time so it is more important than ever to start cutting back on your insurance premiums.

Insider Tips
Insurance is a competitive market. Providers are in the business to make money and deals are not always as great as they first look. Understanding the rules of the game can help you to make a more informed choice about your car insurance. Before you start looking for a policy here are some important insider tips that could save you a lot of money:

Credit Records many people dont realise that their credit record could make a difference to their car insurance premiums. However industry studies have shown there is a direct link between consumer credit scores and car insurance premiums. If you have a poor credit score your premiums will typically be higher. This is because statistically you are more likely to make a claim against your insurance or fall behind with your payments. Having a poor credit score can increase your car insurance risk factor. This means it is important for your overall financial health to keep up with your credit accounts and try to maintain a good credit score.

Car Type the model of car you own affects your car insurance premiums. Insurance companies have a rating system for each make and model of car. This is based on data gathered from national safety, accident and theft reports. It is worth checking how much it costs to insure a car before you buy. You could make a significant saving on your car insurance premiums by simply opting for a car in one of the lower ratings bracket.

Pay Upfront one important insider tip that can save a lot of people money on their car insurance is to pay upfront. Insurers can charge you a lot more for the privilege of spreading your costs out across the year in monthly or quarterly payments. Another benefit of paying upfront for the whole year is that you will not have to worry about any missed payments. This is a good idea if you have a lot of credit product repayments to manage every month.

Minor Claims try to avoid making too many small claims on your car insurance if you can. Minor incidences costing under 1,000 can soon add up on your insurance record and send your premiums soaring. You will save money overall if you pay out for small claims yourself and save your insurance for when it is really needed.

Modifications you must inform your insurance company of any modifications to your car. This can include something as simple as fitting alloy wheels. If you fail to report modifications to your insurer this could invalidate any claims later on. Modifications can push premiums up so think twice whether they are really necessary before you start upgrading your vehicle.

If youre going to work in automotive painting and auto detaining, here are three crucial tips to take into account.

1. Who car detailers are and what they do
Car detailing includes the interior and exterior cleaning and detailing of engines, they are responsible for making minor repairs, removing swirls and defects, polishing, removing stains and grease car wash, vacuuming and shampooing upholstery, paint protection, buffing and waxing, and cleaning wheels. In addition to these duties and responsibilities, many technicians who begin a career in custom car detailing pursue automotive painting.

2. Get yourself a basic education
While car detailing experts do not need to attend a full four year study at a university, it is important to enter the automotive career field with some official training. Many community colleges and technical, vocational schools offer two year degrees and certifications in automotive detailing. Some programs can be taken in less than three months and offer education on the fundamentals of chemical use, use of industry-specific tools and equipment, safety, education on complete engine and body detailing, and knowledge of how to price their services and helpful business practices.

3. Improve and build upon that education
While it can be very tempting to simply finish the most basic of coursework and launch yourself in a car detailing job within half a year, persons wanting a more long-term career should consider continuing their education and possibly working as an apprentice. The U.S. Bureau of Labor Statistics suggest that persons who simply operate within the confines of car detailing make between $20,000 to $30,000 a year, whereas those skilled in automotive painting and employed as auto body and paint technicians can earn as much as $80,000 a year. Journeyman auto body and paint technicians build on the basics they learn as car detailers and add to this knowledge the ability to remove and install auto body panels, parts, and glass, the ability to completely prepare a vehicle for paint, detail work, and the skill to use high transfer paint equipment. Learning these skills in an automotive school gives you a better understanding of industry-standard methodology, and a degree officialises your education for your future employers. Of course, choosing to work as a car detailer and apprenticing as an automotive painter under an established technician is a great way to get hands-on training while being paid.

To be successful in automotive careers like car detailing you need to have passion for the work, have a basic education, and be willing to continue and improve upon the founding blocks of your education. Careers should be open to advancement, allowing you the freedom to grow and mature as an automotive-based technician. For more information, contact an automotive school near you today.

Stepper motors are used for accurate, repeatable positioning such as machine tool applications or for moving the head in an ink-jet printer. By using an electronic controller that applies electrical pulses to the motor windings, the motor shaft can be rotated in either direction in multiples of the step angle, which can range from 0.720 (500 steps per revolution) to 150 (24 steps per revolution). Stepper motors are available with rotational accuracies on the order of 3 percent of a step, which is noncumulative as the motor is stepped back and forth. By controlling the rate at which pulses are applied to the windings of the stepper motor, speed can be varied continuously from a standing stop to a maximum that depends on the motor and load. The three main types of stepper motors are:

1.Variable-reluctance stepper motor 2.Permanent-magnet stepper motor 3.Hybrid stepper motors

The permanent-magnet stepper motor, which has a cylindrical rotor (called a tin-can rotor) that is permanently magnetized with north and south poles alternating around its circumference. The stator of the permanent magnet motor is similar to that of the reluctance motor. As in the reluctance type, the rotor position is stepped by applying a sequence of pulses to the stator windings. Hybrid stepper motors that combine variable reluctance with permanent magnets are also available.

Conventional dc motors are particularly useful in applications that require high speeds and in those for which dc power is available, such as those in aircraft and automobiles. However, because they contain commutators and brushes, conventional dc motors have several disadvantages. These include relatively short service lives due to brush and commutator wear, particularly at very high speeds. Also, arcing as the brushes move between commutator segments can pose a hazard in explosive environments and can create severe radio interference. A relatively new development, the brushless dc motor, provides an excellent alternative when the disadvantages of conventional dc motors are prohibitive. Brushless dc motors are essentially permanent-magnet stepping motors equipped with position sensors (either Hall Effect or optical) and enhanced control units.

As in the stepper motor, power is applied to one stator winding at a time. When the position sensor indicates that the rotor has approached alignment with the stator field, the controller electronically switches power to the next stator winding so that smooth motion continues. By varying the amplitude and duration of the pulses applied to the stator windings, speed can be readily controlled. The result is a motor that can operate from a dc source with characteristics similar to those of a conventional shunt dc motor. Brushless dc motors are used primarily in low-power applications. Their advantages include relatively high efficiency, long service life with little maintenance, freedom from radio interference, ability to operate in explosive chemical environments, and capability for very high speeds (50,000 rpm or more).
