An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...

The idea of winding inductive guitar pickups by hand is almost unthinkable. It uses extremely thin wire and is a repetitive, laborious process that nevertheless requires a certain amount of precision.

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 ...

This is the second half of a two-part article discussing principles and application of the AC induction motors that provide motive power for most of the equipment HVACR engineers specify. In March, we ...

Industry demand has spurred the use of small precision motors and linear actuators. Choose wisely. A few characteristics of dc motors maintain linear relationships that allow for very predictable ...

Motors can be wired delta or wye. Which arrangement do you choose, and how do you do it? For purposes of making the connection, it doesn’t matter to the installer if the motor is delta-wound or ...

Full-voltage, single-speed motor starters: Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters.

A dynamometer is a testing device that helps engineers collect data for various mechanical loading conditions that a motor or engine might encounter in a particular application. Other than testing the ...
