If the motor is not stored for more than three months or more, it is necessary to do some checks before starting before use; Like three-phase asynchronous motors, if stored for too long, then we need to check the insulation resistance of the motor and starting equipment before starting.

       Normally we use500VThe insulation resistance measured by the meter should not be less than0.5Megohm. If it's less than that, then we should be rightThree-phase asynchronous motorFor drying treatment, the drying method can be selected to work in a natural ventilated environment or a drying oven.

       According to the connection on the motor nameplate, check whether the connection is correct, which is very important, and it is generally indicated that it is usedYperhaps△; If the ends of the winding are confused, it can be found according to the correct method of finding the ends.

       It is also necessary to check whether the grounding or zero protection of the three-phase asynchronous motor housing is reliable and meets the safety requirements; You can rotate the motor shaft by hand to check whether the bearing rotates flexibly; Before starting, should also carry out a period of no-load test run, if all normal, in the load test run.

       Three-phase asynchronous motor manufacturersReminder: When running with load, if there is abnormal sound or no rotation, it should be stopped immediately for inspection.
