英文摘要：

A linear o and stability for the scillatory motor with two divided stators was presented to achieve the high efficiency short reciprocating movement. The driven source is one-phase. The mechanical oscillating frequency is the same as the power frequency. It is easy to stack the stator iron similar to the rotary motors. Magnetic reluctance model and finite element method are used to analyze the motor＇s properties and design criterions. Experimental results accorded with analysis results. The magnetic force is proportional to the winding current, and the curve of magnetic force within the maximum stroke is smooth under a constant winding current.
