4 motors essential to machinery

Since the first industrial revolution, motors have been integral parts of machinery. The past 30 years alone have seen greater efficiencies, design standardization, noise reduction and increased power.

This article from Automation World, an Endeavor Business Media partner publication, explores innovations and identifies the four major types of industrial motors: ac induction (also known as asynchronous) and ac synchronous motors, as well as dc synchronous motors and servo motors.

It also looks at the use of variable-frequency drives (VFDs) with single- and three-phase induction motors.
