The torque-load angle relationship is an essential parameter governing the characteristics of SMs. Conventionally, for each load angle, a transient magnetic field model using the time-domain finite element method (FEM) needs to be solved, and hence it is very time-consuming to obtain the complete characteristics of SMs. In this paper, a fast variable phase method, which computes the transient process of the time-domain FEM once only and not repeatedly, is proposed to find the entire torque-load angle curve of SMs. By adjusting the time-step size and the nonlinear iteration error tolerances, the proposed method can significantly reduce the computing time when compared with those of conventional methods. | URI: | http://hdl.handle.net/10397/35528 | ISSN: | 0018-9464 | EISSN: | 1941-0069 | DOI: | 10.1109/TMAG.2014.2321372 |
