Super-efficient 1500-watt 6-pole three-phase asynchronous motor

Abstract

The invention provides a super-efficient 1500-watt 6-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 systematically and reasonably, and stator winding loss, rotor winding loss and iron core loss are reduced greatly. Under the condition that output power is at 1500 watts, compared with existing similar products, the rotating speed is promoted from 911 r/min to 946 r/min, total power loss is reduced from 515.9 W to 259.1 W, energy conservation reaches 49.78%, energy conversion efficiency is improved from 74.4% to 85.3% and improved by 10.9%, the energy conversion efficiency is 2.8% higher than the highest international grade standard 82.5%, 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 1500-watt 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. 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...
