Electromagnetic Design of Toroidal Permanent Magnet Linear Synchronous Motor
For the permanent magnet linear synchronous motors (PMLSM) with high-speed and large-thrust under the periodic transient conditions, the corresponding length and cost requirements are large. This paper designs a toroidal long primary PMLSM.
