Electric permanent magnetic coupler

Abstract

The invention relates to an electric permanent magnetic coupler. The electric permanent magnetic coupler is composed of a conductor rotor, an electric permanent magnetic rotor and a telescoping electrode mechanism. The conductor rotor wraps the radial face and the circumferential surface, the conductor rotor is formed in a way that a high-permeability layer is attached to a high-conductivity layer, the high-conductivity layer faces the electric permanent magnetic rotor, and the high-permeability layer is arranged outside the high-conductivity layer; the electric permanent magnetic rotor comprises a diamagnetic substrate, the diamagnetic substrate is provided with a high-coercivity main permanent magnet and a low-coercivity electric permanent magnet which are arranged at an interval, and the main permanent magnet is connected with the electric permanent magnet through a magnetizer; the electric permanent magnet is wrapped by a magnetizing coil, and two ends of the magnetizing coil are respectively connected with two conducting rings; and the telescoping electrode mechanism comprises an electromagnetic system and a contact system which is contacted with the conducting rings. The electric permanent magnetic coupler is convenient to process, assemble, transport and install, and a motor does not need to be moved backwards.

Description

technical field [0001] The invention relates to the technical field of transmission shaft coupling drive, the technical field of load speed regulation and the field of power drag, in particular to an electro-permanent magnetic coupler capable of controllably adjusting the transmission of magnetic coupling torque. Background technique [0002] In today's society, in various industrial occasions and people's production and life, the fields involving drive shaft drive and speed regulation are very extensive, and the common ones are motors, internal combustion engines, and steam turbines.

Problems solved by technology

However, there are still some defects and deficiencies in its design, such as: the air-cooled heat dissipation design is not advanced; the permanent magnetic coupler takes up axial space, and the motor needs to be moved back, which brings about re-construction of the installation foundation. Cannot be applied; the air gap adjustment mechanism, propulsion mechanism, bearing shafting and electric actuator are complicated and have a high failure rate; the daily inspection and regular maintenance requirements are high; the speed regulation range is narrow; the magnetic eddy current occurrence rate and utilization rate are low, and the thermal efficiency High; the water-cooled cooling system is cumbersome, and the cooling water has damage to the equipment and mineral heat accumulation
