Abstract

PURPOSE: To decide necessity for inspection and exchange properly and easily by gradually increasing applied voltage from zero by a variable transformer for a power circuit and deciding a holding within the tolerance of a reference data of a voltage value and a current value at that time.
CONSTITUTION: A voltmeter 7 and an ammeter 8 are connected previously to the power circuit side of a motor M. Supply voltage applied to the motor M is increased gradually from zero volt by moving variable transformers 5 in a power circuit. The voltage value and current value of the motor M are measure at that time when the motor M starts its revolution, and both values are compared with a previously prepared data. A holding within a tolerance of a difference among both values and the data is judged, thus deciding the presence of the overhaul and exchange of a bearing. Accordingly, the presence of the necessity of the release of the bearing is selected easily, thus reducing the number of the exchange of the bearing.
