Minicar BLDC, Psim simulation, multi-level sensorless signal generating method


If used to drive the minicar, the BLDC Motor has advantages of weightless, efficient, small-size and credibleness. In this paper at first the position detecting method for BLDC was introduced, secondly the simulation of control algorithm was done and at last the prototype controller based one chip processor MEGA48 was fabricated. The controller proposed has characteristic of cheap cost, reliable performance and totally meeting demands of minicar control. Through the Psim simulation and real test we proposed a novel multilevel commutating signals generating method.
