【Abstract】 Rare earth permanent magnet brushless direct current motor (REPM BLDCM) is a novel technology as well as a new product that has been rapidly developed in recent years. It not only incorporates the advantages of traditional DC motor and asynchronous alternating current motor, but also gets over both of their deficiencies. Therefore REPM BLDCM is getting more and more widely used.Referring to relevant datum, and based on the author’s work practice, this dissertation carries out a comparatively penetrative and systematical study on the computer control technology applied to REPM BLDCM.First in this paper, the essential makeup and work principle of the motor system is briefly expatiated. Then its control strategies are discussed;In succession, the thesis introduces the characteristics and control methods of a particular kind of REPM BLDCM, which has no position sensor on its rotor. Also, it gives a design project of both open loop and close loop control system of such kind of motor, based on ASIC TDA5140A;Afterwards, the timing system of elevator door drive device adopting REPM BLDCM is introduced in detail, presenting the overall system project design, hardware and software design of the control system, and software imitation;In addition, after analyzing the technique peculiarities of motor used in electric vehicles (EV), the discourse brings forward a dual-direction control means for EV composed of REPM BLDCM, researching into the structure of AC/DC type dual-direction converter;At the end of this paper, the foreground of REPM BLDCM and its relevant technologies is described.更多还原
