As a first embodiment of the invention, when the piston is in simple harmonic motion, it is necessary to generate a sinusoidal potential, i.e. the flux linkage V varies linearly with displacement X during the motion stroke. Because the sine function is close to linear change near the zero point, if the vibration interval is selected near the curve zero point, the induction potential which is approximate to sine can be generated under the condition of simple harmonic vibration, and because the three-phase type phase winding can not be simultaneously positioned in a proper motion interval, the motor designed by the invention adopts the single-phase type winding.

As a first embodiment of the invention, the structure designed by the invention adopts a fractional groove structure, thereby reducing the positioning force and reducing the difficulty of manufacturing a prototype.
