A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

AutomationDirect has added new NEMA 4X AC drives to their IronHorse brand of drives. These new high-performance VFDs support four control modes including V/Hz, slip compensation, sensorless vector, ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

Precision automation systems and instrumentation equipment manufacturers depend on motion components in applications from micro-mechanical assembly to optical scanning. PI offers a wide range of ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...
