Abstract

A new hybrid double stator bearingless switched reluctance motor (HDSBSRM) realizes the decoupling of torque and suspension force from the structure, and the permanent magnet added in the inner stator further reduces the suspension power loss. For HDSBSRM, loss is the main cause of temperature rise. In order to ensure the stable suspension and rotation of the motor, loss of the Magnetic Bearing (MB) and motor are calculated and analyzed by finite element method (FEM). Based on the loss result, the temperature field is analyzed. The analysis of loss and temperature field provides important theoretical basis for the design of motor cooling system.
