【Abstract】 A certain type of permanent magnet DC servo hollow cup motor was taken as an example, and ANSYS Maxwell was used to build a three-dimensional finite element analysis model.Material properties were assigned to the parts and excitation sources were set, and the magnetic field distribution in the steady state and the output characteristics in the transient state of the model were obtained by improving the external circuit settings and the mesh dissecting method. The comparison of simulation and measured results of three motors was conducted. The results showed that the error between simulation and measured values was within 5%, which verified that the finite element analysis method had high accuracy and provided a theoretical basis for the forward design and optimization of this type of motor.更多还原
