Crane motors overview for you to learn on overhead crane motor, gantry crane motor, hoist crane motors, etc. Types of crane motors, such as, Soft start crane motor, Three-in-one crane, motor, Wound type crane motor are presented for you. Know advantages of each type of crane motor, and get the ideal motor for your crane. 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. 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. 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.
Types of crane motors: Soft start crane motor, Three-in-one motor, Wound type motor
Crane Motor Types and Advantages
In the crane field, the crane motor is AC three phase asynchronous motor. Conical type rotor motor This type of crane motor is used for Single Girder Overhead Cranes, double girder overhead cranes, Single Girder Gantry Cranes, and Jib cranes. 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. (a) Soft start type crane motor Soft star type crane motor and application on overhead crane Motor Brand: Nanjing special brand Advantage of soft star type crane motor • (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 motor and its application on EFM Electric hoist Motor Brand: SZW/SEW/ABM Advantages of Three-in-one-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. (c) Wound type crane motor This type crane motor is used for double girder overhead crane and Double Girder Gantry Crane and Electric Winch. 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.
Wound-type crane motor and its application on a crane trolley Motor brand: Jiamusi / New Dali Advantage of wound-type crane motor • (1) Good starting performance (starting current is only 1.5 – 2.5 times rated current) • (2) Large starting torque • (3) Speed stability
