made in china three phase ac high efficiency electric motor

Line maintenance in 1,the motor should be always kept clean,there is no debris into the motor

internal;Air inlet and outlet must be kept free of traffic.2,use instrument monitoring power supply

voltage,frequency and the load current of the motor.Power supply voltage,frequency,to comply with the

electricalmotor1.blogspot.com motor nameplate data,motor load current shall not exceed the specified value,the plate of or to find out the reason,take measures to bad situation to eliminate the rear can continue to run.3,take the necessary means to each part of the test motor temperature rise.4,for wound rotor type motor,often pumps should pay attention to the contact pressure between the collector ring and brush,wear and spark.When motor stalling,should disconnect the switch inside the stator circuit,then brush lifting mechanism to start position,disconnect short circuit device.Regular maintenance after 5,motor operation,minor repair,overhaul two general points.Minor repair is a general maintenance,not big to the motor start device and a whole disassembly,about one in the first quarter,overhaul to all parts of all transmission device and generator rotor and statormotor is removed,and will remove the components of a comprehensive inspection and cleaning,usually once a year.
