Single-phase brushless DC motor (SPBLDCM) has always been difficult to accurate computer-aided analysis, design and optimization for the lack of appropriate mathematical model of the motor. However, due to simple structure and high efficiency, it is widely used in low cost applications that require low starting torque. In the paper, a linear steady model of SPBLDCM is developed to predict the performance...
Magnetization quality is one of key factors determining the performance of single phase brushless direct current (BLDC) motor and high speed production line requires better magnetization quality test method. In this paper, the relationship between back electromotive force (BEMF) and magnetization of permanent magnet (PM) is thoroughly analyzed, and a novel practical BEMF test method based on the winding...
