Abstract

Background: In this paper, a two-pole 3 kW three-phase induction motor is taken as an example to establish a two-dimensional finite element model. The correctness of the model is verified by comparing the finite element calculation data with the experimental data.

Methods: On this basis, the influence of electromagnetic characteristics of different shell materials on the motor yoke saturation degree, loss, current and power factor are studied, it is determined that the motor yoke saturation degree is the key factor affecting the power factor, current and loss of the motor. The influence of different stator yoke thickness on the saturation degree of motor stator yoke with the same shell material is further studied. The influences of motor stator yoke saturation degree on motor current, loss and power factor are obtained when the stator yoke thickness is different.

Results: The optimum range of motor current, loss and power factor is obtained.

Conclusion: Finally, by comparing the different shell materials to optimize the motor structure size, it is determined that the motor stator yoke thickness can be reduced by using cast iron shell, and the motor materials consumption can be saved to provide reference for motor optimization design.

Keywords: Three-phase induction motor, stator yoke thickness, cast iron shell, cast aluminum shell, copper loss, power factor.
