The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0056] Reference below Figures 1-17 A motor 1 according to an embodiment of the present invention is described, and the motor 1 is installed in an air conditioner.

[0057] According to the motor 1 of the first embodiment of the present invention, the air conditioner has an entire electric control unit 132, such as Figure 17 As shown, the motor 1 may include a motor body 11, an end cover 12 and an electric control board 13. The motor body 11 and the end cover 12 are fixedly connected to jointly define an installation space 14. The electric control board 13 is formed with a motor electric control part 131 and a whole machine electric control part 132. The three-phase winding power line 111 of the motor body 11 is connected to the electric control board 13, and the electric control board 13 is arranged in the installation space 14.

The motor and the whole machine's electronic control occupy a large space as a whole, which cannot meet the consumer's demand for miniaturization of air conditioners. At the same time, the motor power cord will generate interference power and interference voltage when passing through the components of the whole machine. The motor power cord is exposed inside the air conditioner. When the inside of the whole machine is in a high temperature and high humidity environment, it will corrode the component pins, etc., which will have a certain impact on the life of the whole machine.

[0059] Based on this, the embodiment of the present application proposes a motor 1 for an air conditioner, the air conditioner has an entire electronic control unit 132, the motor 1 may include a motor body 11, an end cover 12 and an electronic control board 13, the motor body 11 and the end cover 12 may be fixedly connected by bolt connection, clamping, etc., the motor body 11 and the end cover 12 are fixedly connected to define an installation space 14, such as Figure 5 、 Figure 6 As shown, the electric control board 13 is formed with a motor electric control unit 131 and a whole-machine electric control unit 132.
