Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment.

[0015] Such as figure 1 As shown, the present invention includes two main parts of the stator 1 and the rotor 2, the basic material, structure and manufacturing method are the same as the common 18500 watt 2-pole three-phase asynchronous motor, the difference is that the inner diameter of the stator 8 is made 14.5cm, and the stator punch The groove shape of the sheet groove 6 is made into a trapezoidal groove, wherein the groove bottom width 61 is made into 10.60mm, the groove upper part depth 62 is made into 22.20mm, the groove shoulder height 63 is made into 1.20mm, and the groove shoulder width 64 is made into 8.00mm. The mouth width is 65 to make 3.50mm, the notch height is 66 to be 0.80mm, the center line 9 of the stator buckle slot is passed through the middle of the two slots of the stator punching slot, and then assembled into the stator core 4, the length of the stator core...

Abstract

The invention relates to an ultra-energy-saving 18500W two-pole three-phase asynchronous electric motor, which comprises a stator and a rotor. The inner diameter and the iron core length of the stator, the groove shape and the size of a stator punching sheet groove, the inner diameter, the outer diameter and the iron core length of the rotor, and the groove shape and the size of a rotor punching sheet groove are optimized and reasonably designed, so the stator winding loss, the rotor winding loss and the iron core loss are greatly reduced, on the premise that the output power is identically 18.5kW, the total loss quantity of the exiting similar product is 2523.1W, the total loss quantity of the ultra-energy-saving 18500W two-pole three-phase asynchronous electric motor is only 1481.9 W and is reduced by 41.26 percent, and energy sources are greatly saved. Compared with the energy source conversion efficiency of the existing similar product being 88.0 percent, the energy source conversion efficiency of the ultra-energy-saving 18500W two-pole three-phase asynchronous electric motor is 92.7 percent and is improved by 4.7 percent. Meanwhile, because the center line of a stator buckle sheet groove is designed to penetrate through a position between two grooves of the stator punching sheet groove, the radial electromagnetic force wave in an air gap is weakened, the electromagnetic vibration is reduced, and the electromagnetic noise is lowered.

Description

technical field [0001] The invention relates to a motor, in particular to a super-energy-saving 18500-watt 2-pole three-phase asynchronous motor. Background technique [0002] The motor has a history of nearly 200 years since its inception, and the three-phase asynchronous motor has a history of more than 100 years. At present, it is widely used in various industries such as industry, agriculture, forestry, animal husbandry, and various fields of life. The necessary equipment in industrial production and people's life, but at the same time it has also become the electrical equipment that consumes the most energy in production and life, so how to make the motor energy-saving and environmentally friendly has become an important issue in front of people. China is the largest power consumer in Asia, and is also the developing country with the most serious power shortage in the world. Since 1992, China's annual power generation and power consumption have ranked second in the worl...
