PURPOSE:To eliminate the loss which will be generated due to excitation by a method wherein the magnetic field, which contributes generation of the torque as a motor, is supplied by a permanent magnet. CONSTITUTION:A plurality of permanent magnets 32 are arranged along the inner circumferential surface of a rotor yoke 29 using the end section of a flange 31 as a stopper and a permanent magnet rotor 26 is formed by fixing the above using an adhesive agent. On the other hand, a stator 25 is fixed on a stator fixing cylinder 33 with a laminated steel plate section 41, the stator fixing cylinder 33 is fixed in the protruded section 34 on a stator fixing frame 28, a stator 25 is suspended and inserted in such manner that the gap located inthe inside of the permanent magnet rotor 26 is maintained. Further, an insulating material is applied on the outer circumferential surface of the protruded section 34 on the stator fixing frame 28, on the inner surface of the hollow section 35 and the lower surface of the stator fixing frame 28 using coating process and the like, and the gap (d) located between the winding 27 on the stator 25 and the stator fixing frame 28 is reduced. |
