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 ...

Our objective in specifying motors for HVACR equipment is to start and run the driven equipment under all operating conditions reliably and with reasonable life expectancy. The manufacturer of the ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

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.

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
