Hybrid and Special Linear Permanent Magnet Motors

5.1 Permanent Magnet Hybrid Motors

5.1.1 Finite Element Approach

The magnetic circuits of stepping motors are frequently highly saturated. Therefore, it is often difficult to calculate and analyze motor performance with consistent accuracy by using the classical circuital or field approach. Using the finite element method (FEM) or other numerical methods, more accurate results can be obtained. Since the hybrid linear stepping motor (HLSM) consists of two independent stacks, it is acceptable to model each stack separately. There is one potential difficulty in the modeling of the HLSM. This arises as a result of the tiny air gap, below 0.05 mm. For better accuracy of the calculation, the air ...
