Abstract
PURPOSE:To improve torque characteristic in taking advantage of a dead space, by providing an extended auxiliary pole section and by letting the part face the outside circumferential end face including the winding leg section of a stator core. CONSTITUTION:To multiple unit magnets 2 cylindrically installed to the internal side of a yoke 1a an extended auxiliary pole section 2d projected on one side end face towards the axial centre is formed in sequence to the inside circumference 2b. A stator core 3 is provided concentrically opposite to the inside circumference 2b of unit magnets 2 of a rotor 1 through a specified clearance section 9. 3a is its salient poles. Opposite to the circular exposed surface 3b of both end faces on the outside circumference of the stator core 3, the extended auxiliary pole section 2d of each unit magnet 2 will face with a magnetic clearance 11 between them. As the whole of an exposed surface 3b on the outside circumference of the rotor core facing the extended auxiliary pole section 2d receives the flux from the extended auxiliary pole section 2d, the torque characteristic of a motor is improved.
