Abstract

The invention discloses a speed regulation motor, which comprises a motor body and a speed regulation system wherein the speed regulation system is connected between the motor body and a zero line and includes at least two series-connected impedance elements and at least two switch elements for controlling the connection or the disconnection of the impedance elements to and from the speed regulation system. The speed regulation motor provided by the embodiment of the invention has a wider speed regulation range. The production cost of the speed regulation motor can be favorably reduced, the production efficiency is improved and more qualified products can be yielded.

Description

technical field [0001] Embodiments of the present invention relate to motor technology, and in particular to a speed-regulating motor. Background technique [0002] Because of its simple structure and reliable operation, single-phase asynchronous motors are widely used in household appliances such as air conditioners, electric fans, and refrigerators. [0003] In the prior art, single-phase asynchronous motors generally adopt motor tap speed regulation, PG chopper speed regulation, etc. Motor tap speed regulation is divided into L-type speed regulation (secondary phase tap speed regulation) and T-type speed regulation (main phase tap speed regulation). speed regulation). Motors using the above speed regulation methods have high cost, low production efficiency, and poor motor noise. Moreover, because of the complicated manufacturing process, the defective rate of motor products is relatively high, and the speed regulation range of the motor is limited. Contents of the inve...
