Abstract

Due to the existence of induced eddy current, the internal of the permanent magnet coupling’s temperature increases during the operation, which affects the performance of the permanent magnet coupling. In this paper, considering the influence of temperature on the remanence, coercive force of the permanent magnet, the conductivity of the conductor and steel frame. We analysed the coupling performance of thermodynamics and electromagnetism. Electromagnetic field simulated with ANSYS Maxwell and temperature field simulation with Workbench. The analysis results lay a foundation for the subsequent analysis of the thermo-magnetic coupling of the permanent magnet couplings.
