Abstract:  In response to pitch motor which has high fluctuating and a large variation range of load , a DC series motor with commutation winding and compensation winding was designed using the flexible equivalent magnetic circuit. Magnet, the finite element software, which was used to compare the flux fields, simulate and optimize the design scheme. Simulation and experimental results show that the motor suppressed the armature reaction, which was overloaded with good performance of commutation has 3.7 times overload capacity, meeting the demands of application.
