Motor bearing wear detecting device |
摘要 |
Reinforcing rings are provided around the cylindrical outer surface of a stator can of a canned motor, near the front and rear ends of a stator of the canned motor respectively. An axial position detecting coil A is wound around the cylindrical outer surface of at least one of the reinforcing rings. The axial position of a rotor is detected by an inductance of the axial position detecting coil A. The axial position detecting coil A is installed by winding a coil around at least one of the reinforcing rings. The invention reduces the influence exerted by change in the radial position of the rotor on the output to the axial position detecting coil A to a negligible level and enables detection of the axial position of the rotor and axial zero adjustment without the necessity of considering change in the radial position of the rotor.
