Design of Sine-Wave Control System of BLDCM Regarding a New Permanent-Magnet Material


Article Preview

The Brushless Direct Current Motor (BLDCM) is in nature of high power density, high reliability and easy control etc, growing with the development of microcomputers, new power electronic devices, control theories and low cost rare earth permanent magnet material. The applications of a new permanent magnet material are described in this paper,such as in manufacture of parts of stereo,automobile devices,medical instruments and computer hardware, etc.Besides,the paper also discusses the prospect of its development and the problems in its production.Aiming at the BLDCM with a Hall rotor position sensor, a motor drive controller is designed by pure hardware approach. In this paper, a simple design procedures is described that can be implemented to decrease the material cost of a BLDCM often found in domestic appliances and automotive applications. According to the experiment’s result, this controller has the advantages of easy debugging, high anti-interference ability, larger driving power, low volume and low cost in large scale production.
