BEARING SYSTEM FOR MOTOR
Document Type and Number:
Japanese Patent JPH09229065
Kind Code:
A
Abstract:
To rotate a motor without causing problems such as vibration, noise, friction, and abrasion, at high speed, and in the stable condition.
In a motor provided with a stator 12 and a rotor 16, air is injected from an air injection means 32 into a gap between the stator 12 and the rotor iron core part 18 through an air injection port 30 and an air passage 28. As a result, static pressure is applied onto the inner diametral face 24 of the stator 12, and the stator 12 can be used as the static pressure bearing of the rotor 16.
