Embodiment Construction
[0021] The present invention will be further described below in conjunction with embodiment.
[0022]As shown in the figure, the present invention includes two core parts, the stator and the rotor. The basic material, structure and manufacturing method are the same as those of the common 18500-watt 4-pole three-phase asynchronous motor. The difference is that the stator outer diameter 11 of the stator core 3 is made 30.0cm, the stator inner diameter 12 is made 19.2cm, the length of the stator core 3 is made 22.0cm; the stator punch heat sink 5 is added to the stator punch 1, and the stator punch groove 6 and the stator buckle groove 4 combined to form a stamping structure; the number of stator stamping slots 6 is made into 36 and evenly distributed in a ring shape, and the slot shape is made into a round-bottomed slot with inclined shoulders, and the slot width 61 is made into 3.60mm , the notch height 62 is made 0.80mm, the upper part depth 63 is made 20.20mm, the groove shou...

A 18,500-watt 4-pole three-phase asynchronous motor, including a stator and a rotor. Due to the systematic optimization of the outer diameter, inner diameter, core length, number, slot shape and size of the stator and rotor, the stator Winding loss, rotor winding loss and core loss are greatly reduced; under the premise of the same output power of 18500 watts, compared with existing similar products, the total energy loss of the present invention is reduced from 2126.7W to 1378.1W, a reduction of 35.2%. The required input power has been reduced from the original 20.627kW to 19.878kW, and the energy conversion efficiency has increased from 89.7% to 93.1%, an increase of 3.4%; and the latest national standard "GB18613-2012" which will be enforced in September 2016 Compared with the standard 92.6%, the energy conversion efficiency exceeds 0.5%, which greatly improves the energy conversion efficiency; the application and promotion of the present invention will provide strong support for my country's energy saving and emission reduction work.
Description
technical field [0001] The invention relates to a motor, especially a 18500-watt 4-pole three-phase asynchronous motor. Background technique [0002] Energy conservation and emission reduction is an unavoidable topic in today's world, affecting the living environment of human beings and the development of the world economy. As the key industrial field of energy saving and emission reduction. Among them, the energy-saving potential of the motor system is huge, and the electricity consumption accounts for about 60% of the country's electricity consumption, which has attracted the attention of all parties. 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...
