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. In industrial production, some equipment requires high starting performance and faces high stall risk. The voofu Stall Protection Permanent Magnetic Coupler performs excellently, providing smooth transition during startup, reducing starting current impact and mechanical stress, and extending equipment life. During stall conditions, it quickly senses and adjusts, limiting torque transmission to prevent motor burnout and component damage, making it suitable for equipment such as crushers.

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. Buffered soft start, extending equipment service life.

2. Torque limiting, automatic stall protection.

3. Tolerates large mounting misalignment, simple installation.

4. Overload protection, improving motor system reliability.

5. Simple construction, low maintenance requirements.

6. Design life of 30 years.

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

8. Suitable for harsh environments; generates no pollutants.

9. Generates no harmonics.
