Abstract
A DSP (Digital Signal Processor) (15) controls at least a magnetic bearing (23), and compares the accumulated actual work time of a managed component counted by a counter (14) with a preset maintenance time. The DSP (15) outputs a signal instructing the start of the maintenance operation of the managed component, based on the comparison result.
Claims24
A magnetic bearing control device for controlling a magnetic bearing for supporting a rotor in a non-contact manner, said magnetic bearing control device comprising:
- a digital processor which controls said magnetic bearing using a magnetic bearing control signal and that generates a command signal in response to outputting said magnetic bearing control signal;
- and
- a counter that starts accumulating and counting an actual work time of said magnetic bearing in response to receiving said command signal from said digital processor,
- wherein said digital processor performs a comparison between the accumulated actual work time of said magnetic bearing counted by said counter and a preset maintenance time, and outputs a signal indicating a start of a maintenance operation of said magnetic bearing on a basis of a result of the comparison.

A magnetic bearing controller comprising:
- a processor that controls a magnetic bearing using a magnetic bearing control signal and that generates a command signal in response to outputting the magnet bearing control signal;
- and
- a counter that accumulates and counts an actual work time of a managed component in response to receiving said command signal from said processor,
- wherein said processor further compares the accumulated actual work time with a preset maintenance time.
1 more element
A method for controlling a magnetic bearing comprising:
- controlling said magnetic bearing using a processor that provides a magnetic bearing control signal;
- generating a command signal using the processor in response to providing said magnetic bearing control signal;
- receiving the command signal in a counter;
- counting and accumulating an actual work time of said magnetic bearing using said counter that counts and accumulates the actual work time in response to receiving the command signal;
- and
- comparing said actual work time and a preset maintenance time using said processor.
