MOTOR-INTEGRATED MAGNETIC BEARING DEVICE

Title:

MOTOR-INTEGRATED MAGNETIC BEARING DEVICE

Document Type and Number:

Japanese Patent JP2001086704

Kind Code:

A

Abstract:

To obtain a motor-integrated magnetic bearing device, the operation of which can always be controlled stably, without having to perform readjustment, resetting, etc., of the troublesome control characteristics of magnetic bearings.

In a motor-integrated magnetic bearing device, which supports the rotating shaft 11 of a motor by means of magnetic bearings 14A and 14B, and at the same time, is driven by means of motors 12 and 13, the bearings 14A and 14B and the drive section of the motor are supplied with electric power from a common power supplying section 20 and a motor drive power source section 23, which suppress the fluctuation of the electric power supplied to the motor to a prescribed value or smaller with respect to the power supply fluctuation in the power supplying section 20 is provided.
