Study on performance of toothed conductor permanent magnet governor based on finite element analysis

The torque regulation characteristic is one of the key performance indicators of PMGS. Optimizing these characteristics is crucial for improving the overall performance of the permanent magnet governor. To address the problem of limited speed regulation range at high load in traditional cylindrical governors, a toothed deformable conductor cylindrical permanent magnet governor was designed. The output torque and eddy current distribution of the toothed conductor were simulated in detail using the ANSYS Maxwell software. The simulation results show that, under the condition of full coupling and low slip, the output torque of the permanent magnet governor with toothed deformable conductivity is slightly lower than that of the traditional model, but the speed regulation range is significantly expanded, and the speed response is more uniform. This indicates that the toothed deformation of the electrical conductivity can effectively expand the speed control range and improve the speed control performance, providing powerful technical support for the development of permanent magnet governors.
