Essential learning about induction motors – basics of AC drives and VFD


PID controller – a PID is the most commonly used feedback controller. A PID controller calculates an “error” value as the difference between a measured process variable and a desired set point. The Pid controller attempts to minimize the error by adjusting the process control inputs. The PID controller calculation involves three separate constant parameters, and is accordingly sometimes called three-term control: the proportional, the integral and derivative values, denoted P, I, and D. .

Auto tune controller – Auto tune controller provide economical control for a wide variety of processes, including heating, cooling, and heat/cool. When auto tune controller is used with the proper transmitters, these devices can also control pressure, flow, humidity, motion, or pH. The front panel is NEMA 2, 3R, and 12 rated for waterproof protection and are corrosion resistant. The sophisticated design of auto tuner controller incorporates the latest microprocessor and surface mount technology, compressing an unprecedented number of standard features into a compact 1/16 DIN package. The user can program control functions from the front panel; input types are DIP switch selectable. Multiple tuning modes allow the user to select from 3 standard tuning presets, manual tuning, or auto tuning.

Electronic motor drives into two categories: AC and DC. A motor drive controls the speed, torque, direction and resulting horsepower of a motor. A DC drive typically controls a shunt wound DC motor, which has separate armature and field circuits. AC drives control AC induction motors, and-like their DC counterparts-control speed, torque, and horsepower. A VFD controls the speed, torque and direction of an AC Induction motor. If you are not using VFD you are wasting energy and throwing money out the window. An AC drive may be considered by them as the variable frequency inverter and motor combination. It may even include the motor’s pulley.People in the electrical field and electrical suppliers usually refer to a variable frequency inverter unit alone, or an SCR power module alone (when discussing DC drives) as the “drive” and the motor as the “motor”. Manufacturers of VFD used to refer to the drive as an “adjustable speed AC drive”. To make matters worse when a motor is included in the package it may be referred to as an “adjustable speed AC drive system”.

A VFD is an adjustable speed drive. Adjustable speed drives include all types; mechanical and electrical. About AC drives, the main power components of an AC drive have to be able to supply the required level of current and voltage in a form the motor can use. The controls have to be able to provide the user with necessary adjustments such as minimum and maximum speed settings, so that the drive can be adapted to the user’s process.

Injection Moulding Controller – Manufacturers of Injection Moulding Controller provide total closed loop control for any Injection molding controller.

Rc Cars Toys For The Big Boys


Speed enthusiast? Monster-lover! Then look no further than the universe of RC cars.
Why RChobbies?

RC cars have been around since the 40s, where only the elite had access to the relatively expensive hobby. But the heart-racing sport is not an outdated one. Today RC hobbies have occupied a niche in the commercial market, with RC vehicle sellers owning websites for online shopping.

The fact is RC cars arent just a substitute to real cars. Although most are modeled after life-sized automobiles, there is a difference in how they work. By the name itself, its pretty obvious that you get to do a lot of finger work in driving these m miniature babies. Certainly there is no possibility for a ride, but any enthusiast can vouch for the pride RC hobbies provide. Who wouldnt be happy to own hot rod and a monster truck at the same time?
Also, unlike real thing, an RC vehicle can do back flips and drifting without any real prospect of injury. Because build-your-own (kit-type) and ready-to-race (pre-assembled) cars come with parts and accessories, you dont need a mechanic to repair any damage — just DIY, and youre good to go.

Which RC Car?
Generally RC cars are classified as toy-grade or hobby-grade. Toy-grade cars are just that: pretty cars with nice interior work that are either too heavy or too weak to do anything. The motor isnt for racing, and crashing one damages it for life. These small machines are primarily designed for children. Hobby-grade cars are for the serious RC racers, who need strength, stability, and speed to win competitions such as those sponsored by the International Federation for Model Auto Racing. Online shopping usually is a fast way for purchasing both these types.Those taken with RC hobbies usually choose between an off-road and an on-road car. Either way these cars can be driven by a methanol-castor oil-nitro methane mix in a two-stroke engine, or by an electric motor run by a battery. The power sources of these different types can be bought with online shopping.

The first type, called a nitro RC car, is more popular in that it sounds similar to real cars and even gives off smoke. This car is faster than electric-driven ones, but needs appropriate maintenance to clean unburned fuel. The second type, also called a lipo RC car, should be regularly hooked to an electric outlet to recharge the nickel/lithium-powered battery. It is much cleaner than its nitro counterpart, but needs a cool-down period after a race to avoid overheating.RC cars are available from different manufacturers, either through online shopping or through store outlets. Popular brands include HPI, Associated, Traxxas, and Losi.

How much?
The price of RC cars ranges from $75.00 (A-Tech monster) car to a $1650.00 (Beetle Off-Road 4WD) and above. The cost depends on both the model and the manufacturer, with some makers more expensive than the others. For further information regarding RC Hobiies and products, please visit Shop At Home.

How Brushless Motors Work And Why We Need Them


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.

Ways To Turn Your Car Into Mobile Marketing


Good marketers are always looking for ways to promote their business. If they are not marketing their business in some form, then they feel that the moment is wasted. They use whatever they can to get the message through that they have something to sell, and do whatever they can to sell it. It is thus only natural that they would find a way to use their car as part of their marketing strategy.

The usual method is to use magnetic stickers on the side of a car either owned by the business owner or one hired to drive around with the advertisement on his car. Mobile wraps are also used, but the magnetic stickers are cheaper. In order to work, the ad must stand out, prompting the use of bright colors or color photos to draw attention to the car. Advertising a contest can also work; in some cases advertisers have a random drawing based on entrants that have submitted pictures of the car or information on the car’s location when spotted.

If the business owner decides to hire someone to drive around with the advertisement, then they need to keep in mind certain issues. The advertisement tends to work best on cars that are new or otherwise grab attention, such as older cars or cars that are unique; some companies have actually had a car designed and built or modified specifically for their business. City drivers are obviously preferred, as more people will see the car, and the driver must drive a certain number of miles a day in order for it to be worth the employer’s money. As long as a person is willing to abide by certain conditions, it can actually be profitable to even have their car wrapped as a moving advertisement.

Although vinyl wrap can be used, most people use magnets to turn their car into a company car. This allows the car to switch modes, allowing it to act as a personal car as needed; there are just some times when coming in with advertisements is not acceptable. Also magnets can look more professional than wrapping, especially as wrapping tends to the brighter and more garish. Nonetheless, a company is more likely to get more business, especially in areas where there are constant jams.

One issue that needs to be noted is that the cost of driving may be a possible deduction. Although the IRS frowns on using company cars as a deduction due to their use as personal transportation (the use needs to be delineated, and that is harder to do than most people think), the mileage can still be a source of deduction. Nonetheless, using a car as a roving advertisement can be an effective means of marketing even a small business.

Heritage Motors Customer Testimonial


Are looking to buy a used car or truck? My name is John Sellers and I recently had the pleasure of buying a used car and truck from Steve Curry at Heritage Motors in Medford Oregon.

We moved back to the valley in August of 2009 after leaving in 1983. I was in the need of a truck for my construction business that I could use to drive to and from job sites and to do hauling with. I was referred to Steve at Heritage by multiple members of my family. In the last 20 years they had bought over 10 cars from him.

Visiting the lot came with the normal trepidation that comes with buying a car. However, I was very comfortable with Steve and told him what I was looking for and that I was prepared to spend about $16,000. After carefully listening to me, he recommended that I get two vehicles. One would be a work truck that was older so I did not have to worry about it getting scratched and that would have great hauling power. The other would be a more comfortable car for driving around town.

I loved the idea, but the first words out of my mouth were “I am not spending more then $16,000!” Steve said with a smile on his face “John, if you like the car & truck that I am thinking about, you will spend less than $13,000”.

Well, needless to say, I got a great deal on two vehicles and I spent less than $12,500. The truck is an F250 that is a real work horse and the car is a Jeep Cherokee. It has been 4 months and having both vehicles has worked out even better than expected. In fact, my wife likes the Jeep so much that she is making me drive her Suburban!

I highly recommend that if you are thinking about buying a used car or truck from a dealer in Southern Oregon that you visit Steve Curry at Heritage Motors in Medford. Please let him know I recommended him.
