Abstract

The invention provides a new type of speed-regulating electromagnetic coupler. When the electromagnet is fed with current and the input shaft of the motor drives the copper disc to rotate, the copper disc and the electromagnet disc will move relative to each other, forming a slip between the copper disc and the electromagnet disc. Poor, the electromagnet passing the current will generate a magnetic field. According to Faraday's electromagnetic induction principle, an eddy current is generated between the copper disk and the electromagnet disk, and the induced magnetic field generated by the eddy current interacts with the magnetic field generated by the electromagnet. Due to the slip angle The magnetic force generated by the displacement drives the electromagnet disk to rotate with the copper disk in the same direction, and transmits the torque of the driving shaft to the load end, and then drives the load to do work. By changing the magnitude of the external access current and changing the strength of the electromagnet, the speed regulation function is realized. .

Description

technical field [0001] The invention relates to a novel transmission device, in particular to a novel electromagnetic transmission device. Background technique [0002] With the development of modernization, the speed-regulating transmission devices commonly used in mechanical equipment include speed-regulating hydraulic couplings, frequency conversion and speed-regulating magnetic couplings. The speed-regulating hydraulic coupler has low speed regulation accuracy and serious environmental pollution; the frequency conversion speed regulation has a large impact on the power grid, and the connecting parts are rigidly connected, which is easy to damage the connecting parts; the existing speed-regulating magnetic coupler is due to the permanent magnet material Due to price constraints, it cannot be used for high-power speed-adjustable transmissions. [0003] A new type of speed-regulating electromagnetic coupler is an application of the current magnetic effect. When the metal w...
