초록

This paper presents the torque calculation method of a permanent magnet spherical motor. To calculate the torque of the spherical motor by using finite element method (FEM), 3-dimensional FEM must be used. However since it spends too much time and memory in using 3-D FEM, the easier torque calculation method was presented. In this method, it is very important to get the approximation function of the torque profile curve; the authors present the approximation method of the torque profile curve. This paper shows the torque calculation result coming closer to the torque by 3-D FEM.
