Which motor is used in overhead crane?

The motor whose rotor speed is equal to (or even greater than) the speed of the stator rotating magnetic field is a synchronous motor. There are many types of motors for bridge cranes, which are generally special motors for lifting, that is, there is a letter Z in the motor model. There are wound motor and tapered rotor motor (hook), etc. The motors on the crane are reversible. The motor of crane mostly adopts winding motor, which has a large starting torque and is very suitable for lifting machinery
