Embodiment Construction

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

[0015] like 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 those of the common 18.5kW 4-pole three-phase asynchronous motor. The groove shape of the groove 6 is made into a round-bottomed groove with inclined shoulders. The groove bottom radius 61 is made into 4.90mm, the depth of the upper part of the groove is 62 into 20.20mm, the groove shoulder height 63 is made into 0.65mm, and the groove shoulder width 64 is made into 6.50mm , the notch width 65 is made into 3.60mm, the notch height is 66 and is made into 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, and the stator core 4 The length of the rotor is made into 22.0cm; then the rotor out...

Abstract

The invention relates to an ultra-energy-saving 18500W four-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 existing similar product is 2126.7W, the total loss quantity of the ultra-energy-saving 18500W four-pole three-phase asynchronous electric motor is only 1402.1W and is reduced by 34.07 percent, and energy sources are greatly saved. Compared with the energy source conversion efficiency of the existing similar product being 89.7 percent, the energy source conversion efficiency of the ultra-energy-saving 18500W four-pole three-phase asynchronous electric motor is 93.0 percent and is improved by 3.3 percent. Meanwhile, because the center line of a stator buckle sheet groove is designed to penetrate through the 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 4-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. my country is the largest power consumer in Asia, and is also the developing country with the most serious power shortage in the world. Since 1992, my country's annual power generation and power consumption have ranked second i...
