Core Loss Reduction in Axial Flux Permanent Magnet Motors Using Tooth Shaping

Behrooz Rezaeealam (Lorestan University, Iran)

The performance of axial flux permanent magnet (AFPM) motors can be adversely affected due to the magnetic saturation. The flux density distribution and the magnetic saturation can be affected by the tooth shaping. In this paper, the tooth shaping technique has been used to reduce the core loss, and the optimal results have been then compared with those obtained from the basic model. The results show that the trapezoidal form of stator teeth has been effective to reduce the core loss. In addition to the core loss reduction, the using of tooth shaping technique leads simultaneously to increase in the output torque and the reduction in armature reaction effect on permanent magnets.
