Permanent Magnet Synchronous and Brushless DC Motor Drives Ramu Krishnan
Publisher: CRC

Construction, principle of operation, control and performance of permanent magnet brushless D.C. Usual monikers include ECPM (electronically commutated permanent magnet), BLDC (brushless dc), or just a brushless permanent magnet motor. All production hybred vehicles made by GM currently us a permanent magnet synchronous brushless motor driven by a similar flux vector drive. Construction, principle of Synchronous Reactance – Sinewave motor with practical windings - Phasor diagram – Torque/speed characteristics - Power controllers - Converter Volt-ampere requirements. For making a 160hp motor for the Volt. There are basically two types of synchronous motors: self synchronous motor may be called by various names. Krishnan, “Modeling, Simulation and Analysis of Permanent – Magnet Motor Drives, Part 2: The Brushless DC Motor Drive, “ IEEE Trans, Ind. Miller, 'Brushless Permanent Magnet and Reluctance Motor Drives', Clarendon Press, Oxford, 1989. Toshiba has channeled its capabilities in motors and inverters into an advanced drive system designed to significantly cut power consumption in commuter trains. DC motors are more expensive to build cuz of the permanent magnets, but it takes way less engineering to get them to work, so in that regard it makes sense why GM used a brushless DC motor to get the autoshow Volt to move 10 feet onto the stage. However, recent advances in power control circuitry have given rise to synchronous motor designs optimized for use in such higher power situations as fans, blowers, and to drive axles in off-road vehicles.
