Design and Analysis of a Novel Linear Vernier Motor with Split Tooth Structure

In this paper, a novel linear double-side permanent magnet vernier motor(LPMVM) is proposed. The advantages of high thrust density, low thrust ripple, normal force elimination and stable structure are introduced in detail. The novelty of the proposed motor is substantiated by doubleside structure and toroidal winding, and the primary side adopt the split tooth structure. Compared with the traditional linear permanent magnet synchronous motor, the proposed motor has high thrust density which is achieved by magnetic gear effect. The topology and operation principle of the proposed LPMVM are introduced. The basic characteristics are analyzed by finite element analysis(FEA) further.
