Novel Brushless DC Motor is a new structural motor designed on the basic of traditional Brushless DC Motor, which adopt double sets of salient-pole stator and rotor and use centre excitation coil instead of rotor permanent magnet, with the characteristics of high air-gap flux and large starting torque. The structure and operation principle are introduced in this paper. Through the three- dimensional model built on the general parameters of the motor structure, the electromagnetic and mechanical performances are analyzed by using the 3-D finite element method. Then the mo- tor’s performance has been tested by no-load experimental. The simulation and experimental re- sults verify that the motor has traditional Brushless DC Motor’ characteristics of simple structure and high reliability, and has the advantage of high efficiency and great capacity to expand speed, which ha
