ABSTRACT:
A stator for a magnetic motor comprising a cylindrical yoke, at least one pair of main magnetic poles formed of permanent magnets fixed to the inner peripheral surface of the yoke, at least one pair of auxiliary magnetic poles made of a soft iron material each placed at a side portion of each of the main magnetic poles, wherein an air gap formed between the inner peripheral surface of each of the main magnetic poles and the outer peripheral surface of an armature rotatably placed at the axial center of the yoke is made greater than an air gap formed between the inner peripheral surface of each of the auxiliary magnetic poles and the outer peripheral surface of the armature.
