Abstract

The invention provides a compressor and an air conditioner. The compressor is used for the air conditioner; the compressor comprises a shell, a plurality of wiring terminals, a stator, a rotor, a pump body, a control circuit, and a microcontroller; the stator is provided with multiple phases of windings; one end of each winding is connected with one corresponding wiring terminal while the other end is connected with another corresponding wiring terminal; one end of the control circuit is connected with the power supply while the other end is connected with the wiring terminals for controlling the power-on condition of the windings; the microcontroller is used for detecting the bus voltage of the control circuit, the voltage drop generated after a current passes through the windings, the intra-line counter electromotive force of the windings and the turnover number of the pump body within unit time in real time, wherein when the compressor is in operation and when the turnover number within unit time is less than a preset turnover number, the microcontroller gives out a first signal to control the control circuit to enable one ends of each phase of the windings to be connected with the power supply and enable the other ends to be connected together so as to realize star-shaped connection of the windings. By virtue of the compressor disclosed in the invention, the operation reliability and adaptivity of the compressor are improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor, an air conditioner, and a method for controlling the power-on mode of compressor windings. Background technique [0002] At present, the motor of the frequency conversion compressor is generally a permanent magnet synchronous motor, and the input to the motor side of the compressor through the frequency converter is a three-phase sine wave current. The casing of the compressor is provided with terminals, and the terminals are provided with terminals . The three-phase current converted by the inverter is connected to the motor inside the compressor through three terminals. The wiring method of the motor of the compressor has a star connection method and a delta connection method. When the star connection method is adopted, one end of the three-phase winding of the motor of the compressor is connected together, and the other end is respectively connected to thre...
