Design and Analysis of Brushless Motor for Ball Screw Drives

Abstract

As the Application Specific Electric Motors (ASEM), design and analysis of the brushless motor for ball screw drives are presented. Since the motor should be designed as the built-in structure for the machining equipment, the motor dimensions are restricted. The new design concept for such applications is presented. Under various number of combinations of motor dimensions and electric parameters, the motor performances are simulated by the personal computer, among which the optimized parameter combination can be selected. Based on the optimized parameters, the prototype motor is constructed to prove the validity of the proposed design procedure.
