Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See Figures 1 to 2 The utility model provides a specific technical implementation scheme for punching sheets used in air conditioner outdoor unit motors:

[0021] A punching sheet used for an outdoor unit motor of an air conditioner comprises: a stator punching sheet 1, a small stator slot 2, a large stator slot 3, a slot 4, a rotor punching sheet 5, and a rotor slot 6; the stator punching sheet 1 is a sheet-like structure with an overall annular appearance, and the small stator slots 2 and the large stator slots 3 are arranged at the edge of the inner circle of the stator punching sheet 1; the small stator slots 2 and the large stator slots 3 are each provided in six groups, and the six groups of small stator slots 2 and the six groups of large stator slots 3 are alternately distributed, and each group consists of two small stator slots 2 or two large stator slots 3, with high slot fill rates falling on the large slots and low slot fill rates falling on the small slots, which can effectively solve the difficulty of wire embedding in the production process and improve the one-time qualified rate of the motor. At the same time, the slot design area of the small slots can be fully utilized, thereby improving the efficiency of the motor and saving costs.

[0023] The rotor punching 5 is a sheet structure with an overall circular appearance, and the rotor punching 5 is installed on the inner side of the stator punching 1; the rotor slot 6 is opened at the edge of the outer circle of the rotor punching 5, and the rotor slot 6 is inclined and evenly distributed in multiple places. The length direction of the rotor slot 6 and the radius direction of the rotor punching 5 where the rotor slot 6 is located form an angle of 2-5 degrees, and the angle is preferably 4 degrees, which can make the air gap magnetic field more uniform, and resist the 3rd, 5th and 7th harmonics of the power grid strong, so that the motor runs more smoothly and quietly, and improves the quality of the air conditioner.

[0025] A rotor slot 6 is provided at the edge of the outer circle of the rotor punching sheet 5, and the structure of the rotor slot 6 is changed. The magnetic field is changed by the slot shape. When the magnetic field lines are transmitted through the air gap, the rotor generates a clockwise and counterclockwise rotation force during the rotation process, or generates a force transmission in the rotation direction. Through this force, the rotor generates a smooth self-rotation power in the clockwise or counterclockwise direction, thereby strengthening the resistance to the 3rd, 5th and 7th harmonics of the power grid, making the motor run more smoothly and quietly, and improving the quality of the air conditioner.

The high slot full rate falls on the large punching slot, and the low slot full rate falls on the small punching slot, which can effectively solve the difficulty of wire embedding in the production process and improve the one-time qualified rate of the motor. At the same time, the slot design area of the small punching slot can be fully utilized, thereby improving the efficiency of the motor and saving costs; by setting the slots as straight-edge slots symmetrically distributed on both sides of the stator punching sheet, the cutting cost is saved and the material efficiency is improved. Utilization rate; the rotor slots are inclined and evenly distributed in multiple places, and the length direction of the rotor slots forms an angle of 2-5 degrees with the radius direction of the rotor punching sheet where the rotor slots are located, and the angle is preferably set to 4 degrees, which can make the air gap magnetic field more uniform, and resist the 3rd, 5th and 7th harmonics of the power grid, make the motor run more smoothly and quietly, and improve the quality of the air conditioner; through the improvement of the punching sheet used for the outdoor motor of the air conditioner, it has a reasonable structural design, can effectively solve the difficulty of embedding wire in the production process, improve the one-time qualified rate of the motor, improve the motor efficiency, save costs, resist the 3rd, 5th and 7th harmonics of the power grid, and have the advantages of smoother and quieter motor operation, thereby effectively solving the problems and shortcomings in the existing technology and equipment.
