A type of brushless DC motor with hinged stator and its characteristics were presented in this paper.The motor parameters were designed by the finite element simulation software.Then the sine-wave form of the back EMF was obtained, and the torque ripple was calculated by the finite element simulation.Test of the product driven by sine-wave current was done.The result indicates that the motor with better servocontrol performance offers a choice to servo-driven application with different precisions.
