MOTOR AND APPARATUS INCLUDING THE MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a motor driven by a PWM inverter capable of suppressing the generation of electrolytic corrosion on bearing.SOLUTION: A stator core 11 has a stator coil 12 which is wound being interposed by a resin 21 as an insulator insulating the stator core 11. The stator core 11 is molded with an insulation resin 13 as a molding material along with other fixed components. A stator 10 has a generally cylindrical outer shape with the components parts integrally molded. The stator 10 includes a rotor 14 therein being interposed by a space. The rotor 14 has a disk-like rotor 30 including a rotor core 31 and a shaft 16 fixed to the rotor 30 inserting the center of the rotor 30. The rotor 30 holds a permanent magnet 32 of a ferrite resin opposing to the inner periphery of the stator 10 in a circumference direction.
