MOTOR AND ELECTRIC APPARATUS USING THE SAME
Document Type and Number:
Japanese Patent JP2012239368
Kind Code:
A
Abstract:
To provide a motor inverter-driven by a PWM method, capable of suppressing a bearing from causing electrolytic corrosion.
A motor includes: a stator including a stator core wound with a winding; a rotor facing the stator and retaining a permanent magnet in the peripheral direction; a rotating element including a shaft tightening the rotor to penetrate through the center of the rotor; a bearing supporting the shaft; and two brackets fixing the bearing. The motor is structured so that an axis voltage generated between an inner ring and an outer ring of the bearing is suppressed compared with a withstand voltage of the bearing unit.
