A Simple Design: This machine is made of three windings in the exterior section with a simple rotating section, called the rotor. The AC line voltage causes the rotor to rotate around the axis. Its speed is dependent on only three things: the fixed number of poles, or electromagnetic winding sets, built into the motor; variable speed drives, commonly called inverters or amplifiers, that change the frequency of the AC line voltage; and the amount of force or load on the machine. Changes in speed are expected when the load changes.
An Understandable and Cost-Efficient Design: A permanent magnetic field strength is created in the stator, or stationary section, of the motor by either permanent magnets, which are common in fractional horsepower applications, or electromagnetic windings, which are used in applications that need five or more horsepower.
Speed Control: With this type of machine, controlling the speed is simple. The higher the armature voltage, the faster the rotation, meanings a faster speed. The voltage will increase together with the horsepower. Most DC industrial motors will perform well over a speed stove of 20:1, down to approximately 5 % to 7 % of the base speed. They are designed with variable speed operation in mind, so they have heat control features that allow lower operating speeds.
Load Control: The load, or torque, control is simple. The output torque is proportional to the current, so if you limit the current, you limit the torque it can take. This is one reason why these DC engines are used for applications such as textile manufacturing.
Industrial motors are all around us; owners use them whenever they use appliances and power equipment, while a technician may repair several a day. Chances are you'll use an AC or DC engine before the day is over!
When talking about dream cars, most think of those fancy cars that transform into a towering robot. Every car enthusiast wishes to drive a car that goes faster than any race car on earth. People's mind is full of exceptionally designed vehicle that appears as though it would truly come in the distant future. These ideas however are now closer to reality considering the engineering technology that car makers employ these days.
