Study on Analysis of Torque-Slip Characteristics of Axial Gap Induction Motor

抄録

  In this paper, we propose a high-torque-density axial gap induction motor with toroidal winding. It generates a large torque density because it has a high space factor for reducing motor volume and a wide gap face for improving motor torque. First, the structure and design criteria of the proposed motor are described. Next, the torque-slip characteristic of the proposed motor is compared with the induction motor of the conventional structure, which has the same size. Finally, we show an optimized torque density for the proposed motor. The validity of the proposed motor is demonstrated in a three dimensional-finite element analysis (3D-FEA).
