A Double-Sided Linear Primary Permanent Magnet Vernier Machine

الملخص EN

The purpose of this paper is to present a new double-sided linear primary permanent magnet (PM) vernier (DSLPPMV) machine, which can offer high thrust force, low detent force, and improved power factor.

Both PMs and windings of the proposed machine are on the short translator, while the long stator is designed as a double-sided simple iron core with salient teeth so that it is very robust to transmit high thrust force.

The key of this new machine is the introduction of double stator and the elimination of translator yoke, so that the inductance and the volume of the machine can be reduced.

Hence, the proposed machine offers improved power factor and thrust force density.

The electromagnetic performances of the proposed machine are analyzed including flux, no-load EMF, thrust force density, and inductance.

Based on using the finite element analysis, the characteristics and performances of the proposed machine are assessed.
