Abstract
A motor bearing system has: a slide bearing operable as a gas-lubricated bearing by gas supplied from a pump; a rolling bearing; and a controller. The controller controls the pump such that, when the motor rotation speed is equal to or higher than the first speed and is lower than the second speed, the slide bearing functions as a bearing that supports the rotary shaft and the slide bearing is operated as the gas-lubricated bearing, and when the motor rotation speed is equal to or higher than the second speed, the pump is stopped. In addition, even in the case where the motor rotation speed is equal to or higher than the second speed, the controller does not stop the pump when a radial load applied to the rotary shaft of the motor is equal to or larger than a predetermined value.
