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.

Ferrites and Different Winding Types in Permanent Magnet Synchronous MotorThis paper deals with design of permanent magnet synchronous machines with ferrites. The ferrites became popular due to their low cost and cost increasing of NdFeB. The progress in ferrite properties in the last decade allows the use of ferrites in high power applications. Three models of ferrite motors are presented. It is shown that also the type of stator winding and the shape of the slot opening have an important effect on the PMSM properties. The first motor has a distributed winding, the second motor has concentrated, non-overlapping winding and open stator slots. The third motor has a concentrated non-overlapping winding and semi - open slots. All models are designed for the same output power and they do not have the same dimensions. The paper shows how important the design of an electric machine is for excellent motor properties or better to say how the motor properties can be improved by an appropriate design.
