Abstract: When designing permanent magnet DC motor, chosen angle of commutation have an important effect on performance of electromotor, and choose comfortable angle of commutation is an important method on improving EMC performance of electromotor. Also the analysis is verified by the test result. Use of the improvement measures proposed in this paper, there is a significant improvement for that type of motor electromagnetic interference effects.
