Design and Electromagnetic Analysis of a Double-sided Permanent Magnet Linear Synchronous Motor
The permanent magnet linear synchronous motor (PMLSM) has a good application prospect due to many significant advantages such as high speed,high precision,high thrust force density,simple structure,energy saving and reliable operation etc.,so the research and development are of great importance.This paper mainly focuses on the key design points of a double-sided water-cooled PMLSM.According to the required thrust force,the design is given out including the basic structure parameters,winding connection methods,rated current and water cooling system.Based on the erected finite-element model,the performances such as back-EMF,thrust force,normal force,power factor and efficiency are predicted.By comparing with a single-sided PMLSM with the same specifications,it is proved that this double-sided PMLSM has lower thrust force ripple and higher thrust force density.Moreover,the net normal force of its mover is almost zero.Finally,the predicted back-EMF is verified by measurement.
