Tips: Induction motor doesn’t revolve, why and how to do?

The power source is not connected.
If the power source is not connected or bad contact, the motor will not revolve. At this moment, the electrician must inspect the switch, fuse, various contacts and connection wires. Thus, the fault will be gradually troubleshooting for maintenance.
The fuse is blown out when starting.
Find the reason for the fuse blown, troubleshoot the fault and then fit the proper fuse for the motor.
The setting current of the over-current relay is too low.
For this problem, just regulate higher properly.
The load is too large or the transmission mechanism blocks.
In this case, choose an induction motor with bigger capacity or relieve the load, and also check the condition of the transmission mechanism.
The stator or rotor winding is in open circuit.
Open the terminal box and check if the motor winding is broken (leads breakage) with the Ohm gear of the multi-meter. If any open circuit occurs, the resistance value might be abnormal. It is required to open the motor to make further inspection and connect the breakage point.
