Abstract
A positioning linear motor based on a halbach permanent magnetic array comprises a base plate and a flat plate pulley. Two parallel wheel tracks are arranged on the base plate, and wheels of the pulley are positioned in the wheel tracks so that the flat plate pulley can horizontally move along the wheel tracks. A stator positioned between the two wheel tracks is parallel to the base plate and arranged on the base plate, the stator comprises a stator core wound by insulating tapes, a three-phase winding is arranged outside the insulating tapes of the stator core, and the stator is fixed onto the base plate through a supporting column. The halbach permanent magnetic array is arranged on the flat plate pulley along the direction parallel to the wheel tracks, and an air gap is reserved between the halbach permanent magnetic array and the stator. By means of the halbach permanent magnetic array, force moment of tooth socket effect of the motor is greatly reduced, a more favorable sine distribution magnetic field can be achieved, and a stator skewed slot structure and distributed winding measure can be omitted. Furthermore, the positioning linear motor based on the halbach permanent magnetic array is simple in structure, convenient in manufacturing and low in cost.
