Problems solved by technology

[0006] However, due to the limitations of the working principle, structure and force transmission mode, the existing induction motors have defects such as small torque, low efficiency, large loss, and small mass-to-power ratio at low speeds, which cannot meet special requirements for use. Motors with special properties to compensate

Abstract

The invention discloses a disc type magnetic motor with a permanent magnet and an electromagnet. The disc type magnetic motor comprises a stator and a rotor, wherein the stator is provided with a top block groove, and the top block groove is communicated with a top-holding electromagnet groove; the top block groove is communicated with a drive arm groove in the anticlockwise or clockwise rotationdirection, and the other side of the drive arm groove is communicated with a driving electromagnet groove; the top block groove is provided with a spring groove in the anticlockwise or clockwise rotation direction, and a top block is arranged in the top block groove; a top-holding electromagnet is arranged in the top-holding electromagnet groove, and the top block is provided with a top-holding permanent magnet; a drive arm groove is internally provided with a drive arm, a drive electromagnet is arranged in the driving electromagnet groove, and the drive arm is provided with a drive permanentmagnet; and a spring is arranged in the spring groove. The invention also discloses a working method based on the disc type magnetic motor with the permanent magnet and the electromagnet. The disc type magnetic motor and the working method provided by the invention have the advantages that low speed and large torsion are achieved without additionally arranging a speed-transformation, the relativeefficiency is higher, the loss is small, and the quality power is large.

Description

[0001] technical field [0002] The invention relates to a disc with permanent magnets and electromagnets suitable for positioning and driving in various occasions such as mechanical equipment, precision measurement, metering, office automation equipment, industrial appliances, household appliances, robots, automobiles, aerospace equipment, etc. magnetic motor and its method of operation. Background technique [0003] The working principle of the traditional induction motor is: when the primary winding is connected to the AC power supply, a traveling wave magnetic field is generated in the air gap, and the secondary is cut by the traveling wave magnetic field to induce an electromotive force and generate a current, which is in contact with the air gap Electromagnetic thrust is produced by the interaction of the magnetic fields in it. The electromagnetic thrust is the power of the rotary motion of the rotor of the rotary motor or the linear motion of the mover of the linear ...
