As shown in fig. 1 to 3, according to the structural schematic diagram of the motor 1 for the air conditioner of the present invention, the motor 1 is fixedly provided on the motor bracket 5, the motor 1 includes a rotating shaft 11 having a first end 111 and a second end 112, the first end 111 of the rotating shaft 11 protrudes from the front surface of the housing surface of the motor 1, and the second end 112 of the rotating shaft 11 protrudes from the back surface of the housing surface of the motor 1. The fan blade 2 is disposed at the first end 111 of the rotating shaft 11, and when the motor 1 is running, the motor 1 can drive the fan blade 2 to rotate through the rotating shaft 11. The second end 112 of the rotating shaft 11 may be provided with a locking portion 113, so that the second end 112 of the rotating shaft 11 can be locked and driven with the power generating device 3.
As shown in fig. 1 and 2, the telescopic mechanism 4 is provided on the fixed bracket 6, and the power generation device 3 is connected to the telescopic mechanism 4. The basic positions of the telescopic mechanism 4, the power generation device 3 and the rotating shaft 11 are on the same straight line. Thus, when the air conditioner outdoor unit is in the first state, the telescopic mechanism 4 is contracted in the horizontal direction, so that the power generation device 3 is separated from the second end 112 of the rotating shaft 11, and the motor 1 can drive the fan blades 2 to rotate. In the first state, the air conditioner is in an operating state.

By the mode, the electric energy which is sent out by the power generation device 3 and stored in the storage battery supplements the power consumption of the air conditioner in the standby state, so that the energy consumption loss of the rotation of the fan blade 2 caused by the blowing of the air is reduced, and the standby with zero external power consumption is possible to be realized.
In an embodiment of the present invention, a control method is provided, which may include the steps of:
when the air conditioner enters a stop state or a standby state, the power generation device 3 is connected with the second end 112 of the rotating shaft 11 through the telescopic mechanism 4. At this time, when the fan blade 2 blows to rotate in the wind, it can drive the rotating shaft 11 to rotate, and then the rotating shaft 11 drives the power generation device 3 to rotate to generate power. The electric energy can be stored by the storage battery for use of an external machine main board and/or an internal machine main board and/or a lamp panel of the air conditioner, so that the air conditioner can be standby under the condition that an external power supply is not needed.
Specifically, when the electric quantity of the storage battery is larger than or equal to a preset value, an external power supply is not started, and power is supplied to an external machine main board in the air conditioner external machine, an internal machine main board in the air conditioner internal machine and/or a lamp panel through the storage battery; when the electric quantity of the storage battery is smaller than a preset value, an external power supply is started to supply power to an external machine main board in the air conditioner external machine, an internal machine main board in the air conditioner internal machine and/or a lamp panel.
When the air conditioner enters the running state, the power generation device 3 is separated from the second end 112 of the rotating shaft 11 through the telescopic mechanism 4. At this time, the air conditioner drives the motor 1 to rotate through the external power supply, and the motor 1 drives the fan blades 2 to rotate so as to generate wind, so that the condenser in the air conditioner external unit is cooled. The power generation device 3 is in a non-power generation state.
