Product Introduction:

A permanent magnetic coupler (also known as magnetic coupler, magnetic drive coupler, permanent magnetic coupling, etc.) is a device that uses the magnetic field of permanent magnets to achieve non-contact torque transmission. It is widely used in industrial drive systems, offering significant advantages such as high efficiency, energy savings, and maintenance-free operation. The voofu Coal Mine Safety Permanent Magnetic Coupler is specifically designed for underground coal mine environments, effectively solving the application challenges of couplers with braking devices in such scenarios.

Technical Principle:

When the conductor rotor on the motor side and the permanent magnet rotor on the load side move relative to each other, the conductor cuts through the magnetic field lines, generating eddy currents, which in turn produce an induced magnetic field. This induced field interacts with the permanent magnetic field to achieve non-contact torque transmission. By adjusting the air gap width or coupling area, dynamic control of torque and speed can be achieved to meet various operating conditions.

Advantages & Features:

1. Product certified with coal mine explosion-proof approval.

2. Buffered soft start, extending equipment service life.

3. Torque limiting, automatic stall protection.

4. Eliminates axial drift, resolves vibration in brakes and other devices.

5. Overload protection, improving motor system reliability.

6. Simple construction, low maintenance requirements.

7. Design life of 30 years.

8. Non-contact torque transmission with excellent vibration damping.

9. Suitable for harsh environments; generates no pollutants.
