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 watts 4-pole three-phase asynchronous motor, the difference is that the stator outer diameter 12 is made 18.00cm, the stator The inner diameter 8 is made into 11.20cm, 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 inclined shoulders, and the radius 61 of the groove bottom is made into 3.711 mm, the depth of the upper part of the groove is 62 to make 12.60mm, the height of the groove shoulder is 63 to be 0.47mm, the width of the groove shoulder is 64 to be 5.30mm, the width of the slot is 65 to be 2.50mm, and the height of the slot is 66 to be 0.80...

Abstract

The invention provides a super-efficient 2200-watt 4-pole three-phase asynchronous motor which comprises a stator and a rotor. Due to the fact that inner diameter, outer diameter of the stator and the rotor, iron core length and quantity, groove shapes and sizes of punching grooves are optimized and designed reasonably, and stator winding loss, rotor winding loss and iron core loss are reduced greatly. Under the condition that output power is at 2200 watts, compared with existing similar products, the rotating speed is promoted from 1415 r / min to 1443 r / min and accelerated by 28 r / min, total power loss is reduced from 505.5 W to 293.7 W, energy conservation reaches 41.90%, energy conversion efficiency is improved from 81.3% to 88.2% and improved by 6.9%, the energy conversion efficiency is 1.5% higher than the highest international grade standard 86.7%, and the energy conversion efficiency is improved greatly. Simultaneously, due to the fact that a central line of a stator cramping groove penetrates between two grooves of the stator punching grooves, radial electromagnetic force wave in air gaps is weakened, electromagnetic vibration is reduced, and electromagnetic noise is lowered.

Description

technical field [0001] The invention relates to a motor, in particular to a super-efficient 2200-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 in the...
