Abstract
A power consumption control device includes: a voltage detection circuit configured to detect whether an input power supply of a magnetic levitation system to be controlled is turned off; and a comparison unit configured to detect an operating parameter of a motor of the magnetic levitation system during an operation of the motor as a generator, and compare the operating parameter with a set parameter to obtain a comparison result; a motor controller of the magnetic levitation system controls the motor of the magnetic levitation system to operate as the generator in a case that the input power supply is turned off, a bearing controller of the magnetic levitation system adjusts a magnitude of a bearing bias current of the magnetic levitation system according to the comparison result, to control a power consumption of a magnetic levitation bearing of the magnetic levitation system within a set range.
