Performance Comparison between Surface-Mounted and Interior Brushless DC Motor

摘要：

　　In this paper,the cogging torque,airgap flux density,back-emf,and losses of a surface-mounted and a hybrid magnetization interior brushless machines with the same stator,airgap width,armature core length,material,permanent magnet consumption,speed and copper loss are compared.The analysis reveals that the loss in rotor back iron of interior motor is higher than that in surface-mounted motor due to the skin effect while the eddy current losses in sleeve and magnets of surface-mounted motor are significant,causing the total losses of surface-mounted motor are higher than that of interior motor.
