In order to achieve high torque at low power with high efficiency, a new five-phase permanent magnet brushless DC (PMBLDC) motor design was analyzed and optimized.A similar three-phase motor having the same D/L ratio (inner diameter (D) and length of FIXED BLADE - CLOSEOUT the stator (L)) is compared for maximum torque and torque ripple of the designed five-phase PMBLDC motor.Maxwell software was used to build finite element simulation model of the motor.The internal complicated magnetic field distribution and dynamic performance simulation were obtained in different DEVELOPER 2% 7 VOL positions.No load and load characteristics of the five-phase PMBLDC motor were simulated, and the power consumption of materials was computed.
The conformity of the final simulation results indicates that this method can be used to provide a theoretical basis for further optimal design of this new type of motor with its drive so as to improve the starting torque and reduce torque ripple of the motor.
