What is crane motor?

Crane motor is a part of gantry crane and overhead crane, which is a kind of equipment for electrical energy into mechanical energy. It is through the electric coil (i.e. stator winding) to produce a rotating magnetic field and its function in the form of rotary torque.tPpHenan Dongqi Machinery Co., Ltd

The crane motor is divided into DC crane motor and AC crane motor by using different power. The crane motor power system most of the AC crane motor can be synchronous or asynchronous crane motor.tPpHenan Dongqi Machinery Co., Ltd

The crane motor is mainly composed of stator and rotor, the direction of the force movement in the magnetic field is related to the current direction and the direction of the magnetic induction line. The principle of the crane motor is the effect of the magnetic field on the current force, so that the crane motor rotation.tPpHenan Dongqi Machinery Co., Ltd

Crane motor types and advantages

In the crane field, the crane motor is AC three phase asynchronous motor.tPpHenan Dongqi Machinery Co., Ltd

Conical type rotor motor

This type crane motor is used for single girder overhead crane, double girder overhead crane, Single girder gantry crane, jib crane.tPpHenan Dongqi Machinery Co., Ltd
The conical type three-phase asynchronous crane motor is the stator of the electric crane motor for the three-phase scattered type distribution winding. The rotor is a cage guide.tPpHenan Dongqi Machinery Co., Ltd

Advantage of soft star type crane motor tPpHenan Dongqi Machinery Co., Ltd

  • (1) Locked rotor current is smaller than other crane motors, which can prevent crane motor burning;
  • (2) The starting current is small, it can improve the impact of the starting, the operation noise is small, and the service life of the main control AC contactor is prolonged;
  • (3) It can adapt to frequent start, power saving effect is remarkable;
  • (4) Achieve soft start, it can increase the crane frame and the life of the plant.
(b) Three-in-one type motor

"Three in one" reducer crane motor is reducer, crane motor and brake in one, with the crane motor shaft parallel output, compact structure, large transmission torque, stable work, low noise, long life and so on.tPpHenan Dongqi Machinery Co., Ltd

Wound type crane motor

This type crane motor is used for double girder overhead crane and double girder gantry crane and electric winch.tPpHenan Dongqi Machinery Co., Ltd

The wound type three-phase asynchronous crane motor is the stator of the electric crane motor for the three-phase scattered type distribution winding. The rotor coil ends are not directly lead to short-circuit, but lead to the start control device of slip ring.tPpHenan Dongqi Machinery Co., Ltd
