Analysis of a 1.5kW Induction Motor Through Electromagnetic and Thermal Simulations

This paper investigates a method to predict the rated output performance of a 1.5kW induction motor accurately. This method uses 2D electromagnetic model to calculate the operating point of the motor. In the model, the results of noload test is used to obtain the magnetic property of the laminations used in the motor, the mechanical and core losses, 3D eddy current field analysis is used to calculate the unbalanced three-phase leakage inductances, and thermal analysis is conducted to determine the conductivities of this motor. Finally, the errors between the calculated results and the data given by the manufacturers are within 5%.
