Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] Figure 1(a)(b) shows the principle and implementation diagram of the stator (salient pole core) of the transformer-type asynchronous motor. A and A' in the figure are the two ends of the input winding respectively; B and B' are respectively Both ends of the induction winding; D is a short-circuit ring (shaded pole winding), C is a capacitor, E is a bidirectional diode, and the arrow indicates the direction of current passing through the two salient pole winding wires. Figure 1(a) is a 6-pole motor stator with 6 salient poles; Figure 1(b) is a 2-pole motor stator with 2 salient poles. Each salient pole corresponds to a transformer with primary and secondary windings, the motor stator input winding is connected in series with the primary windings of each salient pole, and the induction winding is connected in series with the secondary windings of each sa...

Abstract

The invention relates to single-phase asynchronous motor in high power factor and efficiency and low wastage of electric energy specially. Based on basic physics: direction of induced current-Chen's law, second law of current direction, principle for releasing induced electromotive force in multiplying factor, self current feed back circuit is built in stator. Thus, induced current is phase shifted 180 degrees. The induced current and original AC current are in same direction and changed in-phase so as to form domino effect in alternating electromagnetic field, reduce current drain and input current. Comparing with prior art, the invention saves electrical energy more than 50%. The invention is applicable to air-condition, refrigerators electrical household appliances, and general electric tools in single phase.

Description

technical field [0001] The invention relates to a single-phase asynchronous motor, in particular to a single-phase asynchronous motor with high power factor and high efficiency and low power loss. Background technique [0002] The operation of the motor is the energy conversion of electricity-magnetism-force. There must be an air gap between the rotor and the stator of the motor to allow the rotating magnetic field to make the rotor rotate and do work. The existence of the magnetic air gap will inevitably increase the loss of electric energy. Therefore, the motor The power factor and efficiency of the transformer are lower than those of the transformer. Single-phase motors generally have small capacity, and the air gap between the stator and rotor of the motor is fixed. The smaller the capacity of the motor, the lower its efficiency. Single-phase motors are widely used in industrial and agricultural production and household appliances. Little drops of water can be merged in...
