  4. Abstract:
  5. Single-phase, outer-rotor squirrel cage induction motors are widely used in ceiling fan applications. Furthermore, they can be employed for pumps, and in-wheel hub drives. In this article, an analytical model based on magnetic equivalent circuit is proposed to evaluate the performance of the motor. The influence of rotor slots' skewing, stator end windings, slots' leakage inductance, and core saturation are included in the model. Furthermore, the windings' copper losses and the core's iron losses are calculated using the proposed model. The results of the presented model are compared with those of time variant finite element analysis (TVFEA) and experimental measurements close agreement between the results confirms the success of the proposed model from accuracy point of view. Furthermore, the computation time required for the proposed model considering the linear and nonlinear cores are 1 min and 11 min., respectively. However, those of TVFEA considering 64 000 mesh elements for linear and nonlinear cores are 21 h and 28 h, respectively. © 1982-2012 IEEE
