Reluctance motor and self-control optical coupled switch and motion control, structure damp and radiating method

Abstract

This invention discloses a three-phase magnetic resistance motor, which replaces the multi-stage rotor core with a ladder-type convex pole with an ellipse two pole rotor core and utilizes a self-controlled light-coupled switch mounted on the axostyle of the rotor to realize location control and frequency self-support having the character of a self-controlled synchronous motor, and its unit volumepower reaches to over 4 times of the present one.

The invention also relates to a method for the electric motor to be powered by three-phase alternating current rectification. Background technique: [0002] The reluctance motor, as a continuous running electrical transmission, is fundamentally different from the traditional AC and DC motors in its structure and working principle. This kind of motor does not rely on the interaction of the...

Problems solved by technology

Because the path of this "short-circuit magnetic flux" tends to be the shortest, but the reluctance cannot be minimized due to the air gap, so the compression of the radial air gap is formed, but due to structural reasons, this The force of radial compression ends up being the main source of electromagnetic noise

[0009] (2) Since the reluctance motor belongs to the electric transmission device with continuous operation, during the continuous shut-off and switching process of the phase winding current, due to the short-term overlapping energization phenomenon between the adjacent stator windings, the adjacent stator windings Vibration and noise are generated due to the same polarity of the magnetomotive force and mutual repulsion

[0010] (3) Because the reluctance motor of the prior art has two kinds of mutation factors, the stepped air gap and the use of switching power supply, on the variable reluctance circuit of the stator and rotor, directly lead to the torque ripple of the reluctance motor, according to At present, with this structure, it is almost impossible to fundamentally eliminate the torque ripple phenomenon of the reluctance motor.

[0011] In addition, the reluctance motor in the prior art also has the defects of low power per unit volume of the motor and complex control system and high cost due to the too small energization interval of the phase winding.
