Description
technical field [0001] The invention relates to the technical field of magnetic transmission equipment, in particular to a composite magnetic coupler temperature precision testing system and a testing method thereof. Background technique [0002] As a device based on permanent magnet eddy current, the magnetic coupling is very important to analyze the temperature rise caused by the eddy current. The eddy current of the magnetic coupler has two meanings. On the one hand, the transmission of torque requires the eddy current in the copper disk to generate a magnetic field to couple with the permanent magnet, thereby generating torque; on the other hand, the power loss of the magnetic coupler is mainly generated by the eddy current. The form is released from the conductor copper disc, which reduces the transmission efficiency of the magnetic coupler. At the same time, the working performance of the permanent magnet will be limited by its Curie temperature. When it is close to o...
