Thrust Fluctuation

The thrust fluctuation optimal design of the tubular permanent magnet linear synchronous motor is the key to sinusoidal flux density wave degree in theoretical analysis. And the paper analyses the law of different parameters on the flux density waveform. The axial magnetized linear motor is optimized. The measures which inhibited thrust fluctuation is obtained. It has guidance action in motor designing. It has practical engineering value.

The One

In order to minimize the detent force of permanent magnet linear synchronous motor (PMLSM) caused by end effect, a novel auxiliary poles one-piece structure is proposed. Two auxiliary poles are extended directly from two ends of the armature core. And magnetic isolation bridges are set between auxiliary pole and armature core. Compared with the conventional discrete auxiliary poles, the one-piece structure will reduce the manufacture difficulty of PMLSM with auxiliary poles and improve the reliability of linear motor.
