What’permanent magnet generator pdf the Difference Between AC Induction, Permanent Magnet, and Servomotor Technologies? Engineers today are tasked with applying myriad motor technologies because most rotary motion is ultimately powered by electric motors. Here we expound on some engineering caveats and compare all three options for specific situations — with a special focus on permanent-magnet motors for engineers who haven’t used them before.

Difference Between AC Induction, Permanent Magnet, and Servomotor Technologies? Jim Murphy, LEESON Electric Corp. Download this article in . This file type includes high resolution graphics and schematics when applicable. AC induction motors, permanent-magnet motors, and servomotors — the three major technologies with partially overlapping functionalities for larger, higher-end applications requiring precisely metered torque, speed, or positioning.

In all its iterations, the induction motor induces magnetism that is leveraged to output rotary motion. Illustrated here are magnet-induced flux and current-induced flux, upon which all electric motor operation is based. As the rotor’s induced current and magnetism cause it to follow the field generated by the stator, rotary motion is output. The rotor current’s effect on the air gap flux causes torque. These AC induction motors are quite common — the workhorse of industry.
