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.

Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

Figure 1. The chart shows energy savings achieved by Refrigeration Service Co. with use of a variable-speed controller. EDITOR’S NOTE: This material was prepared by Heatcraft Worldwide Refrigeration.

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Model VSM-CA3 modulates the speed of motors in fancoil units, fan-powered VAV terminal units, fan filter units, and other air-moving devices. The controller provides modulating control of AC induction ...

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 MDrive34Plus2 Speed Control combines a motor, driver, and encoder, and includes a programmable digital oscillator for accurate, variable-speed control. The device uses a NEMA-Size-34 brushless ...

Variable speed control for electronic drives is a main factor for increasing energy efficiency in machine engineering. With the EFC 3600 variable frequency drive series, Bosch Rexroth offers the ...
