摘要：

The characteristics of the phase unbalance in a moving-coil type Permanent Magnet Linear Synchronous Motor(PMLSM) for travelling the reciprocating trajectory are presented. The phase unbalance caused at end coils, such as deficiency and asymmetry of each phase EMF, is thoroughly investigated. Moreover, a compensating method that can minimize such phase unbalance by adjusting the mechanical air-gap length is proposed, and its effectiveness is verified in a practical application.
