Conductor rotor or p-m rotor are provided with adjusting device, and described adjusting device is used for making conductor rotor or p-m rotor to produce axial displacement, to increase or to reduce both coupling areas.

Conductor loops comprises inside support ring and the outer support ring of the location that cooperatively interacts, and is nested with inner wire ring and outer conductor ring respectively on described inside support ring and the outer support ring, and fixes by holding screw.

Fix by connecting bolt between inside support ring and the outer support ring.

Permanent magnetism torque controller of the present utility model, its moment of torsion transfer principle are the relative motions by conductor and permanent magnet, and the eddy current of responding in conductor and the magnetic field interaction of permanent magnet are realized.

Permanent magnetism torque controller of the present utility model does not have the process of rectification, inversion, and power supply is not polluted, and need not to drop into the harmonic wave control expense.There is not power electronic device, simple control system, can reach 30 years useful life.Product can on-the-spotly be installed, and need not special-purpose running environment, safeguards simple.Be air gap coupling between load and the motor, do not have mechanical connection, the vibrations of load do not influence motor useful life.

The beneficial effect that the technical scheme that the utility model provides is brought is:

1, according to operating mode, can save energy 10%---50%.

2, in 30 year useful life, can reduce cost of investment.

3, electrical network is not polluted, can save control expense, guarantee other power consumption equipment operate as normal.

4, be directly installed on the scene, service conditions is simple, need not facilities such as additional investment machine room.

5, reduce shock transfer, reduce the damaged condition to motor.
