    1Test method. Before the test is powered on, in order to prevent the rotor from rotating due to the torque generated by the induction current in the rotor core during the power on, the rotor should be blocked with instruments in advance. Before blocking, it is necessary to electrify the rotor to see the direction of rotation, and then device plugging appliance. For smaller capacity motors, a stronger board may be used to support the key seat of the motor shaft extension.

    The blocking test under low voltage is a test item, and its purpose is the same as the common cage rotor motor. The voltage applied and the data to be measured are the same as those related to the plugging test in the inspection test of the common cage rotor motor. In the test, the rotor should be blocked, no brush device, the rotor winding should be in the collector ring short circuit or its three-phase lead wire connected in a short circuit; If there is a brush lifting device, place the brush lifting device in the "running" position.
