Energy-saving Permanent Magnetic Coupler of WF-CV
Permanent magnetic coupler (also known as permanent magnetic coupling device, magnetic coupler or permanent magnetic shaft coupling) is a piece of equipment that realizes non-contact torque transmission via the magnetic field of permanent magnets. Widely adopted in industrial transmission systems, it features prominent merits including high efficiency, energy conservation and maintenance-free operation. The energy-saving permanent magnetic coupler developed by Wolfer Permanent Magnet allows manual air gap adjustment to achieve precise speed regulation of pumps and fans, delivering remarkably improved energy-saving performance while maintaining high-efficiency power transmission.
Product Structure:
It consists of a permanent magnet rotor disc (connected to the load shaft) and a conductor rotor disc (connected to the motor shaft), with an air gap between them and no rigid mechanical connection.
Output power:
2.2—7800kW
Rotational speed:
Maximum speed is 7000r/min
Renovation construction period:
1 day
Specification and Model:
Refer to the selection manual

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 Energy-Saving Permanent Magnetic Coupler supports manual air gap adjustment, enabling precise speed control of pumps and fans, significantly enhancing energy savings while maintaining efficient power transmission.


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. Adjustable air gap/speed, energy saving rate up to 5–40%.

2. Non-rigid connection, reducing vibration.

3. Purely mechanical structure, high reliability, simple maintenance.

4. Compact design, small footprint.

5. Low requirements for power grid quality.

6. Permanent magnetic field drives the load, no harmonics.

7. Suitable for harsh environments.

8. Designed for a 30-year service life, with up to 10 years of maintenance-free continuous operation.

9. Effectively protects both motor and load, reducing failure rates.
