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 ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

During the 1990s, scrap yards could choose their shredder drives. The rule of thumb was DC for large and mid-size systems (5000 hp and below) and AC wound rotor for super shredders (6000 hp and above) ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

A quest for energy efficiency has fostered development of switched reluctance motors that are inherently simple and can supply variable speeds. They can be more efficient than induction motors and ...

Hyundai has recently provided an enlightening explanation of how electric vehicle (EV) motors operate, simplifying complex ...

The nine-month project will investigate current and future applications for electric motors, their requirements for armouring sleeves and provide technological insights. Companies interested in the ...

The humble automotive alternator hides an interesting secret. Known as the part that converts power from internal combustion into the electricity needed to run everything else, they can also ...
