Product description:

The torque-limited permanent magnet coupler realizes the torque transmission from the motor to the load through the air gap between the copper conductor and the permanent magnet. This technology realizes the non-mechanical connection between the driving motor and the driven load side. Its working principle is: the conductor rotor is equipped with a copper conductor, and the load end is a multi-pole permanent magnet. When there is relative motion (rotation) between the active and passive bodies, eddy currents will be induced on the surface of the copper conductor corresponding to each permanent magnet, thereby realizing the transmission of torque. When the load is suddenly overloaded or stuck, the rotation speed of the permanent magnet rotor connected to the load quickly drops to zero, while the copper rotor connected to the motor continues to rotate at the speed of the motor. The magnetic induction force generated by the relative speed difference between the two can quickly increase the gap between the two to 38mm (the maximum distance of the gap), thereby eliminating the torque transmission between the motor and the load, and can achieve the purpose of fully protecting the motor and transmission components.

Features:

Product description:

● The motor output shaft is fixed to the conductor rotor, and the load (reducer) input shaft is fixed to the permanent magnet rotor
● The motor starts, driving the conductor rotor to rotate and cut the permanent magnet rotor magnetic field. The conductor rotor generates eddy current, which in turn generates an induced magnetic field, which interacts with the permanent magnet rotor magnetic field and drives the permanent magnet rotor to rotate.

Features:

   
●No physical connection, isolated vibration transmission
●No oiling or power supply, no maintenance required
●Stalling torque limit protection, extending equipment life
●Tolerant centering error, easy to install and disassemble
●Simple and reliable structure, adaptable to harsh environment

Features of Comin Permanent Magnetic Coupler

Case Introduction-Conveyor Belt Replacement Liquid Coupling Retrofit

Conveyor belt renovation of the first steel plant

Fault phenomenon：
The original hydraulic coupler has just been used for one year, and oil leakage is often found; the vibration is out of the normal range, and has been calibrated and aligned many times, which has seriously affected the normal production.

Solve the problem：
It was replaced with a magnetic coupler of the same power and quickly installed and debugged. It has been running without any faults so far.

Actual effect:
Trouble-free greatly reduces maintenance costs and ensures continuous production. It can automatically disengage in case of overload and quickly recover after the problem is solved.

Conveyor belt renovation at petrochemical terminal

Fault phenomenon：
The mucus soft starter is leaking oil badly.

Solve the problem:
Replace it with a magnetic coupler of the same power to achieve the soft start function.

Expected results:
Trouble-free greatly reduces maintenance costs and ensures continuous production. It can automatically disengage in case of overload and quickly recover after the problem is solved.

Case Introduction-Coal Mill Liquid Couple Transformation

A thermal power company

Fault phenomenon：
The original liquid occasionally leaks oil and the vibration is abnormal. The horizontal vibration is 0.55mm and the vertical vibration is 0.48mm.
