Generally speaking, three-phase motors are less troublesome than single-phase motors, having no starting relays or capacitors to deal with. All three-phase units are high-starting-torque motors and ...

In this detailed video, we break down the working principles of one of the most widely used electric motors in industrial applications—the three-phase AC induction motor. Understanding how these ...

Compressor overheating is one of the industry's most serious field problems today. One of the most elusive causes of compressor motor overheating and failure is voltage unbalance. This article ...

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it ...

The new software includes a reconstruction algorithm that uses the phase-shifted trigonometric relationship between current signals of all three phases to accurately deduce negative phase-current ...

Toshiba’s Hall sensorless sine-wave drive three-phase brushless DC motor control pre-driver IC helps reduce vibration and noise of high-speed motors.

A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...
