Embodiment Construction

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

[0015] like figure 1 As shown, the present invention includes two main parts: stator 1 and rotor 2. The basic material, structure and manufacturing method are the same as those of the ordinary 90kW 4-pole three-phase asynchronous motor. The groove shape of 6 is made into a trapezoidal groove, the width of the groove bottom 61 is made 11.20mm, the upper groove depth 62 is made 45.00mm, the height of the groove shoulder 63 is made 1.24mm, the width of the groove shoulder 64 is made 9.00mm, and the notch The width 65 is made 4.00mm, the slot height 66 is made 1.00mm, 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 length of the stator core 4 is made Then make the outer diameter of the rotor 10 into 28.84 cm, the inner diameter of the rotor 11 into 9.5 cm, and mak...

Abstract

The invention discloses a super energy-saving 90kW4 pole three-phase asynchronous motor which comprises a stator and a rotor. As the inner diameter of the stator, the iron core length, the shape and size of a stator stamping tank, the inner diameter and the outer diameter of the rotor, the iron core length and the shape and size the of a rotor stamping tank are optimized and reasonably designed, so that the stator winding loss, the rotor winding loss and the iron core loss are reduced greatly; under the condition that an output power is 11kW, the total loss quantity of an existing similar product is 7098.3W, however the total loss quantity of the super energy-saving 90kW4 pole three-phase asynchronous motor is only 4552.3W, i.e. the loss is reduced by 35.87%, so that the energy is saved greatly; compared with the energy conversion efficiency (which is 92.7%) of the existing similar product, the energy conversion efficiency of the super energy-saving 90kW4 pole three-phase asynchronous motor is 95.2%, that is, the energy conversion efficiency is increased by 2.7%; and meanwhile as the central line of a stator stamping tank is designed to penetrate through the middle part of two tanks of the stator stamping tank, a radial electromagnetic wave in an air gap is weakened, the electromagnetic vibration and the electromagnetic noise are reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a super energy-saving 90kW 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. 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. Mos...
