ROTATING DEVICE HAVING FAILURE DETECTING DEVICE OF HOUSING ROTOR, PROGRAM FOR DETECTING FAILURE AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To detect the failure of the cover rotation in a rotating device covered by a casing. SOLUTION: A control part 200 of the failure detecting device stores a value of torque acting on a motor 400 at predetermined rotating frequency in a state that the rotor is free from the cover rotor in RAM of the control part 200. In the rotation of the cover rotor, a CPU of the control part 200 receives the value of torque acting on the motor 400 at predetermined rotating frequency from an inverter 300, compares and operates the both values, determines the failure when the difference between both values is over a predetermined value, and stops the motor.
