Overview:

Modular design with the motor, the whole machine is divided into torque motor, eddy current brake, electromagnetic brake (with a weather vane), fan four modules according to different functions, different requirements and use the user needs to be configurable, its performance indicators have reached international advanced level, is a domestic initiative, and the utility model patents.

The motor can be set arbitrarily stepless speed regulation in the speed range, with constant power, constant line speed, smooth starting and braking, fast accurate positioning, high above the ground operation such as kinetic energy.

Because the motor is installed in the gear reducer, has the advantages of good heat radiation, convenient maintenance and adjustment and has the advantages of small volume, light weight, beautiful appearance etc..

The utility range:

This type of motor is mainly used for slewing mechanism of tower crane. Also widely used in constant line speed other speed cable, plastics, printing and dyeing, textile, paper and other industries.

Working conditions:

Torque motor has the typical characteristics of high voltage winding, must be in the outside, its speed is approximately linear decrease with the increase of the load torque, the mechanical characteristics of good linearity, which can realize the heavy load and slow speed in the voltage constant, light load fast, good to achieve the unification of safety and efficiency. The applied voltage is changed, the mechanical characteristics of curve along with the change of torque motor. It is possible to obtain mechanical properties similar to the shape of the curve series. The use of the characteristics of the torque motor can be changed by the applied voltage and realize the stepless speed regulation.

Eddy current brake armature rotating with the rotating shaft. When the excitation coil into DC current, claw pole magnetic field generated by cutting magnetic line of force, armature produce inductive magnetic field, forming the current (both eddy current). The magnetic field and the claw pole magnetic field produced by the vortex interaction, produce braking torque. In certain speed range, stepless speed regulation braking torque and excitation current and armature speed linearly proportional linear adjusting excitation current can realize motor.

Torque motor with eddy current brake, the mechanical characteristic of the motor is improved better, the curve is more close to linear can improve the motor soft starting and braking performance, increase the stable starting, braking can smooth soft brake, prevent the rotating speed mutation, Jian Xiaoqi move, brake on the tower arm impact and improve the safety of tower crane operation.
