Problems solved by technology

[0004] Most of the 2,200-watt 6-pole three-phase asynchronous motors currently on the market are IE1 grades, with an energy conversion efficiency of 77.7%, and a small amount of IE2 grades, whose energy conversion efficiency has risen to 81.8%, but their energy-saving effect is still not enough. Meet the current needs of developing a low-carbon economy

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 2200 watt 6-pole three-phase asynchronous motor, the difference is that the outer diameter of the stator 12 is made 19.00cm, the stator The inner diameter 8 is made into 12.40cm, and the number of stator punching slots 6 is made into 36 and evenly distributed in a ring shape. The groove shape of the stator punching slots 6 is made into a round-bottomed groove with oblique shoulders, and the slot width 61 is made into 3.00 mm, slot height 62 is made 0.80mm, slot upper depth 63 is made 13.60mm, slot shoulder width 64 is made 5.45mm, slot shoulder height 65 is made 1.20mm, slot bottom radius 66 is made 4.00mm, and the stator buckle The center line 9 of the slot passes through the middle of the...

Abstract

An ultra-high-efficiency 2200-watt six-pole three-phase asynchronous motor comprises a stator and a rotor. The external diameter and the internal diameter of each of the stator and the rotor, the core length and the number, the shape and the size of punching sheet slots are optimized and reasonably designed systematically to enable loss of a stator winding, a rotor winding and a core to be greatly reduced. With the 2200-watt output power, compared with existing like products, the ultra-high-efficiency 2200-watt six-pole three-phase asynchronous motor has the advantages that rotational speed is increased from 930r / min to 959r / min; total electric energy loss is decreased from 622.9w to 340.3w, and energy is saved by 50.49%; energy conversion efficiency is greatly increased from 77.9% to 87.7%, is increased by 9.8% and is 3.4% higher than the highest international grade standard of 84.3%; and since a central line of a stator cramp slot is designed to penetrate through the middles of two of the stator punching sheet slots, radial electromagnetic force waves in air gaps are weakened, electromagnetic vibration is reduced, and electromagnetic noise is reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a super-efficient 2200-watt 6-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 world. Mo...
