The motor can have a soft start and soft brake, with overload protection that automatically disconnects and resets. The flexible connection effectively eliminates system vibration.

It has low centering requirements, making it easy to install and debug. Additionally, it is maintenance-free and has a long service life.

This equipment is suitable for industries such as steel, mining, coal, chemical, paper, textile, shipbuilding, and cement. It can be used for conveyors, bucket wheels, excavators, elevators, ball mills, crushers, rod presses, and mills, as well as for coal machines, stacker reclaimers, mixers, boiler slag crushers, and other power equipment with power less than 800kW prime mover.

Magnetic Torque Coupling Definition

The magnetic torque coupling consists of a magnet and a conductor rotor with a variable air gap. When the main motor rotates the conductor rotor, it opposes the magnet installed on the driven end. The rotor conductor generates an eddy current-induced magnetic field during circular motion at the active end. This field interacts with the magnetic field at the driven end, allowing for non-contact torque transmission.

When the machine is overloaded or stuck, the air gap between the magnetic rotor and the conductor rotor rapidly increases until it reaches the point where the speed of the magnetic rotor at the machine end decreases or reaches zero. This activates the motor’s overload protection. After the overload or stuck condition is resolved, the magnetic and conductor rotors return to their original minimum air gap positions through the recovery mechanism, and the machine resumes normal operation.
