MTC series constant permanent magnet coupler

The constant permanent magnet coupler is composed of two symmetrical disc structures, which can change the output torque by adjusting the air gap between the conductor rotor and the permanent magnet rotor in a small range, so as to realize the torque transmission between the motor and the load. The driving end and the driven end are each composed of two hubs with clearance fit for easy installation. They are connected to the motor shaft and the load shaft by a locking disc, and do not require any keyway or pin for fixing.
When the load exceeds a certain torque limit value, the magnetic induction force will produce an axial repulsive force to enlarge the air gap, so that the load is completely separated from the motor, and the motor is protected from damage.

uproduct description

 

   The constant permanent magnet coupler is developed based on the principle of magnetic induction. It is mainly composed of a conductor rotor and a surrounding permanent magnet rotor. The conductor rotor is connected to the motor shaft, the permanent magnet rotor is connected to the working machine shaft, and the permanent magnet rotor and the conductor rotor form a fixed The air gap never touches. When the motor rotates, the relative movement between the rotors causes induced eddy currents in the conductor rotor, and the magnetic field generated by the eddy current interacts with the permanent magnet magnetic field to realize the torque transmission. When the magnetic rotor is overloaded, it can automatically bounce and pull the air gap to realize unloading. After the load is removed, the permanent disk automatically resets, thus realizing the function of torque limitation and device protection. This kind of overload protection torque transmission method is different from the traditional hydraulic coupler. Its overload response is fast, non-contact torque transmission realizes wear-free, maintenance-free, and has the advantages of vibration reduction and noise reduction, which greatly improves the reliability of equipment operation. The automatic reset function is more stable and reliable. The patented product "inner jacket type locking mechanism" independently developed by Jingji Company completely solves the defects of traditional coupler installation and disassembly, and low reliability.

uScope of application
