Abstract

The invention discloses an air-conditioner outdoor fan starting control method which comprises the following steps: receiving a starting instruction of an air-conditioner outdoor fan; acquiring the first line back electromotive force and the second line back electromotive force of the air-conditioner outdoor fan; acquiring the current rotation station and rotation speed of the air-conditioner outdoor fan according to the first line back electromotive force and the second line back electromotive force; controlling the startup of the air-conditioner outdoor fan according to the current rotation station and rotation speed. Through the air-conditioner outdoor fan starting control method, accurate current rotation station and corresponding rotation speed can be acquired, and starting of the air-conditioner outdoor fan can be controlled according to the current rotation station and rotation speed, so that the starting success rate can be increased greatly, the reliability is high, and the cost is low. The invention further discloses an air-conditioner outdoor fan starting control device and an air-conditioner comprising the air-conditioner outdoor fan starting control device.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method for starting an outdoor fan of an air conditioner, a control device for starting an outdoor fan of an air conditioner, and an air conditioner including the control device for starting an outdoor fan of an air conditioner. Background technique [0002] At present, based on the consideration of energy saving, reducing working noise and reducing costs, users usually use Sensorless FOC (Sensorless Field Oriented Control, sensorless field oriented control) control strategy in a large number of applications in air conditioning systems, especially in outdoor air conditioning fans. A permanent magnet synchronous motor with a sinusoidal back EMF waveform. In the outdoor unit of the air conditioner without position sensor, the working condition of the fan has the situation that the fan blades of the motor have already rotated with the wind or against the wind befo...
