Dynamic Characteristics Analysis of Linear Brushless DC motor using Finite Element Method according to Load Condition

摘要

This paper presents the dynamic characteristics of a linear brushless DC motor with permanent magnet excitation for the precision conveyor according to the load condition. To investigate the accurate dynamic performance of 6-step inverter-fed linear BLDC motor, finite element techniques coupling with external circuit models, together with the simultaneous simulation of motion of the mover system, are proposed. The results of finite element analysis are compared to the experimental ones.
