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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

This month marks the 50th year since ABB’s Low Voltage Variable Speed Drive (VSD) was first brought to market.

October 2025 marks the 50th anniversary of ABB’s Low Voltage Variable Speed Drive (LV VSD). Developed by Finnish engineering ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...
