英文摘要：

Magnetic levitation micromotion stage is easy to realize micromotion with high resolution because a contact-free magnetic levitation technique is used between the moving plate and the driving part. The main parameters of drive circuit and the choice of driving scheme of a magnetic levitation micromotion stage have been discussed. Two circuits based on the driving scheme have been designed and studied by experiments. Finally, the experimental results of the two drive circuits have been analyzed and compared, then, the drive method satisfied the demand of this stage＇s movement has been presented.
