Ultra-efficient 37 kW 6-pole three-phase asynchronous motor

Abstract

The invention provides an ultra-efficient 37 kW 6-pole three-phase asynchronous motor, which comprises a stator and a rotor; as the internal diameter of the stator, an iron core length and the slot shape and size of a stator punching sheet slot, and the internal diameter and external diameter and the iron core length of the rotor, and the slot shape and size of a rotor punching sheet slot are efficiently designed, the stator winding loss, rotor winding loss and iron core loss are greatly reduced; when the output power is 37 kW, the domestic existing similar products require an input power of 40.558 kW, the power loss amount is 3557.7 W, while the input power required by the ultra-efficient 37 kW 6-pole three-phase asynchronous motor is only 39.158 kW, the power loss amount is only 2158.0 W, thus, the power loss amount is reduced by 39.34 percent; the energy conversion efficiency exceeds 3.3 percent of that of the domestic similar products, and 1.2 percent of the highest level standard of the international motor energy efficiency is exceeded. The center line of the stator cleat slot penetrates from the middle of the two slots of the stator punching sheet slots, thus, the radial electromagnetic wave in an air gap is weakened, the electromagnetic vibration is reduced and the electromagnetic noise is reduced.

Description

technical field [0001] The invention relates to a motor, in particular to a super-efficient 37kW 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. Most of...
