Description

technical field

[0001] The invention relates to a motor, in particular to a double-winding asynchronous motor. Background technique

[0002] The current AC frequency conversion technology dominated by PWM technology has better solved the problem of speed regulation of asynchronous motors, but its high device cost, especially for motors that do not require high speed regulation accuracy, actually affects its wide application. . The invention patent with the patent number ZL03145525.5 discloses an "inner compensation winding of an AC motor". On the stator core, two to three winding segments per phase are arranged in a double-layer winding arrangement, and the Three power supply terminals and three compensation terminals are drawn out through the connection mode, and the current phasor in the winding is superimposed with the current of the capacitor connected to the compensation terminal, so that the inductive power of the motor and the capacitive power of the capacitor have a...
