Variable speed motor controllers regulate the speed and/or torque of asynchronous motors. Depending on the application, there are controllers from a few hundred Watts up to several hundred Kilowatts.

In addition to industrial applications of variable-speed motor drives, the home appliance market is another major area where three-phase pulse width modulated (PWM) motor control drives are finding ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

The Eon 42 variable-speed, constant-torque motor is designed for direct-drive blower applications such as fan coils, kitchen ventilators, air curtains, and unit heaters/coolers. According to the ...
