Abstract：The solid rotor asynchronous motor has a large starting torque and is suitable for frequent start and stop situations, but its power factor and efficiency are low, and the axial groove on the rotor surface can be improved. In this paper, the three-dimensional finite element method is used to study the magnetic field of a solid rotor motor. The factors such as core saturation and end effect can be fully considered and compared with the experimental data of the prototype. It is proved that the three-dimensional finite element method can accurately analyze the magnetic field distribution law and working performance of solid rotor motor. In the analysis of the influence of slotting on the performance of solid rotor motor, this paper uses a more intuitive three-dimensional finite element method to analyze the output of the slot change to the motor. The law of the influence of torque. It shows that reasonable slotting can effectively improve the output torque of the motor. It provides a basis for design optimization of this type of motor.
