As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

A nontraditional wiring approach offers midspeed stepmotors high torque with low current. Most engineers in the motion-control industry agree that a common frustration with stepmotors involves finding ...

Power Integrations has released Version 2.3.5 of its PI Expert Online power supply design software. It now features support for a secondary with parallel windings in the transformer construction ...

Often, a simple control scheme using a microprocessor can allow manufacturers to use lower starting torque compressors without the use of a hard start kit to operate their ice machines. Before the ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

HIOKI recently announced the launch of the Impulse Winding Tester ST4030, which is the company’s first instrument to provide functionality for testing for defects in motor windings. HIOKI provides a ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

The internal combustion engine is found in traditional cars as the main traction element disappears and is replaced by new solutions, with electric motor and batteries at the center of the scene. This ...

It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments increasingly legislate efficiency standards. In particular, washing machines, air ...
