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.

When comparing actual dealers, there are many honest dealers out there trying to provide quality used fire apparatus. Unfortunately, there are also brokers that can give the wrong impression to customers that see a large inventory and assume the website is from a larger dealer.

In reality, used fire truck dealers and brokers work hand in hand. Dealers buy, maintain, and sell on property used fire engines that they hand select. When smaller dealers need help selling their fleet, they give their inventory to a broker. brokers can help with marketing and connecting customers to the dealer, but the broker never truly “owns” an apparatus.

How To Buy A Properly Sized Motorcycle Helmet


Before you start your search for a motorcycle helmet, or take the next step towards buying a helmet, you should be aware of how motorcycle helmets are meant to fit. When buying a helmet, how do you know that it fits correctly? Buying a helmet that offers maximum protection requires you to have an understanding of the proper sizing and fit. For both safety and comfort, it is essential that you wear a proper fitting motorcycle helmet. Many new riders end up buying a helmet that is too large. While this may be comfortable, it may not be tight enough to remain on your head during a crash, and will therefore provide less protection than a properly fitted motorcycle helmet.

Most helmet manufacturers have size charts to assist you in choosing the appropriate size. Most helmets come in small, medium, large, and extra-large. Keep in mind that not all helmets are made the same; sizes often vary between manufacturers. Before buying a helmet, you’ll need to have an idea of your approximate size. Measuring the head is a good starting point for determining your correct motorcycle helmet size. Measure around your head at a point about an inch above the eyebrows, which will result in the largest possible circumference. Hat size can be another rough starting point for determining your motorcycle helmet size.

When buying a helmet, always be sure to try it on, either at the store or when it arrives in the mail. When trying on a full face motorcycle helmet, make sure that the helmet rests just above your browline. Try to fit your thumb between the helmet and your forehead. The helmet should rest so closely against your forehead that there is no room left to fit a finger. Conversely, if you feel like the helmet will leave red marks on your skin or it’s so tight that it is uncomfortable to get onto your head, it may be too small. Make sure that it does not obstruct your field of vision. Shake your head to check that the helmet feels secure, not too loose, on your head. If you wear prescription glasses, make sure that you’ll be able to wear them comfortably with the helmet.

If you are a woman, it is also crucial to understand the differences between men’s and women’s helmets. Although these differences are subtle, and you may even not notice any stylistic differences, buying a helmet that fits you correctly is crucial if you want for maximum protection while riding. If you accidentally end up buying a helmet designed for men, it will not fit as well as a helmet designed for women. In addition to potential design variations, most women’s motorcycle helmets are slightly smaller than the same size in men’s motorcycle helmets.

Stylish Motorbike Boots And Other Motorcycle Accessories For Safe Riding


Every off road or biker needs to know that his or her motorcycle accessories are up to the job. Motorbike boots, for example, need to protect the biker from the sometimes extreme conditions that he or she is riding in, as well as the actual mechanics of the bike. As such, when buying accessories like boots for a rider, it is important to take the nature of the sport into consideration.

There are some mechanical aspects of biking that remain the same across all terrains and disciplines. All bikers must lean with their vehicles in some way if they are to get them to turn properly: and all motor bikes have exposed parts (engine boxes and exhaust pipes) that can get extremely hot. As such, motorbike boots have one or two things in common no matter what the terrain or discipline that the motorcycle accessories are intended for.

First up, a good boot needs to maintain a good balance between flexibility and strength, or rigidity. The boot must be flexible enough in the ankle to allow a rider to turn and flex with his or her machine through tighter corners or over obstacles and jumps. However, the boot must also provide enough rigidity around the ankle that a fallen rider does not risk snapping a bone during the dismount.

All motorbike boots need to have excellent thermal protection, particularly on the inside leg, ankle and instep. These are the most likely parts of the anatomy to accidentally touch one of those previously mentioned hot parts of the engine and exhaust system.

When you are looking at new motorcycle accessories, dont forget to consider the environment you or the intended owner of these accessories is likely to be in before and after racing or riding. Off road and dirt bikers, for example, must have the best available grip to the soles of their boots both for maintaining a good controlled grip on the foot studs when riding, and for walking safely in the dirt bike environment, either after a fall or prior to or after a race.

Look for motorbike boots that come all the way up the calf, for maximum grip, fit and protection. Ensure that there is enough room in the sizing to allow for proper protective socks between the boot and the leg not to mention, of course, protective trousers.

Once you have covered all the practical aspects of your motorcycle accessories, its time to turn to their looks. Bikers want to look as cool as their bikes: and that means, finally, picking motorbike boots that have that extra special something in their visual makeup as well as in the ways they stop a rider from coming to harm. Dont ignore the style side of things get boots, gloves, helmets and mask that are as ready to rock as the rider himself, or herself, and you know you have found the right ones.
