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 those of the common 2200w 2-pole three-phase asynchronous motor. The groove shape of 6 is made into a round-bottomed groove with inclined shoulders. The width of the groove 65 is made into 2.80mm, the height of the groove is 66 into 0.50mm, the depth of the upper part of the groove is 62 into 9.00mm, and the width of the groove shoulder is 64 into 6.50mm. The groove shoulder height 63 is made 1.35mm, the groove bottom radius 61 is made 4.20mm, the center line 9 of the stator buckle groove is passed through the middle of the two grooves of the stator punching groove 6, and then assembled into the stator core 5, and the stator core 4 The length of the rotor is made into 13.0cm; then the rotor outer diam...

Abstract

A super-energy-saving 2200w dipolar three-phase asynchronous motor comprises a stator and a rotor. Since the inner diameter and the iron core length of the stator, the shape and size of stator punching plate grooves, the inner diameter, the outer diameter and the iron core length of the rotor and the shape and size of stator punching plate grooves are optimized and designed reasonably to enable the stator winding loss to be only 122.3w, the rotor winding loss to be only 111.0w and the iron core loss to be only 19.0w. On the premise that the output power is 2200w, existing like products require input power of 2.655kw and the energy conversion efficiency is 82.9%, while the super-energy-saving 2200w dipolar three-phase asynchronous motor only requires the input efficiency of 2.536kw and the energy conversion efficiency is 86.7%, so that energy resources are greatly saved, and energy conversion efficiency is improved. The rotation speed is increased from 2849r / min to 2860r / min. Further, since the center line of each stator cramp groove is designed to penetrate between each two stator punching plate grooves, radial electromagnetic waves in air gaps are 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 energy-saving 2200w 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 world. Mo...
