Transient Thermal Analysis Using Both Lumped- Circuit Approach and Finite Element Method of a Permanet Magnet Traction Motor
نویسنده
چکیده
This paper presents the transient thermal analysis of a permanent magnet (PM) synchronous traction motor. The motor has magnets inset into the surface of the rotor to give a maximum field-weakening range of between 2 and 2.5. Both analytically based lumped circuit and numerical finite element methods have been used to simulate the motor. A comparison of the two methods is made showing the advantages and disadvantages of each. Simulation results are compared with practical measurements.
