Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment.

[0016] 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 1500w 6-pole three-phase asynchronous motor, the difference is that the stator inner diameter 8 is made 9.9cm, and the stator punching slot The groove shape of 6 is made into a round-bottomed groove with inclined shoulders. The groove bottom radius 61 is made into 3.55mm, the depth of the upper part of the groove is 62 into 11.98mm, the groove shoulder height 63 is made into 0.66mm, and the groove shoulder width 64 is made into 5.20mm. The notch width 65 is made 2.00mm, the notch height 66 is made 0.50mm, 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 is Ma...

Abstract

The invention provides an ultra energy efficient 1500-w six-pole three-phase asynchronous motor comprises a stator and a rotor. The inner diameter and core length of the stator, the shape and size of a stator punching groove, the inner diameter, outer diameter and core length of the rotor, and the shape and size of a rotor punching groove are optimally and rationally designed, so that the winding loss of the stator is only 159.9 w, while the winding loss of the rotor is only 94.5 w and the core loss is only 10.2 w; in case of the same output power of 1500 w, the input power needed by the existing same product is 2.016 kw and the energy conversion efficiency is 75.4%; however, the input power needed by the ultra energy efficient 1500-w six-pole three-phase asynchronous motor provided by the invention is only 1.794 kw and the energy conversion efficiency is 83.5%; therefore, the energy source is greatly saved; and simultaneously, as the center line of a stator locking groove is designed to penetrate through the middle parts of the two grooves of the stator punching groove, the radial electromagnetic wave in an air gap is weakened, the electromagnetic vibration is reduced, and consequently, the electromagnetic noise is reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a super energy-saving 1500w 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. 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...
