The dual redundant permanent magnet synchronous motor not only has the advantages of wide speed range, fast dynamic response and high power density of the permanent magnet synchronous motor, but also can improve the safety of the motor system. In this paper, for 800w dual-redundant permanent magnet synchronous motor, the internal magnetic field environment is simulated, and the influence of magnetic field on AC loss of high-temperature superconductor is analyzed. By simulating the AC loss of the high-temperature superconductor in the self-field and comparing with the result of Norris formula, the simulation model is verified to be reasonable, which provides a reference for the design of the high-temperature superconducting coil in the dual redundant permanent magnet synchronous motor. |
