Problems solved by technology

[0003] Most of the existing heat pump heating equipment still uses ordinary air-conditioning compressors. However, such ordinary air-conditioning compressors cannot adapt to low ambient temperature, high outlet water temperature, high load pressure, high energy efficiency requirements, and long running time during use. Due to long-term use conditions, the motor is prone to overheating and burning during use. Therefore, it is necessary to develop a heat pump heating equipment that is suitable for harsh air temperature conditions, has high load pressure bearing capacity, high energy efficiency, and can run for a long time, and is suitable for this type of heating equipment. The motor parts of the equipment, specifically, the development of a high-torque, high-efficiency, high-reliability motor has become a technical problem to be solved urgently by those skilled in the art

Abstract

The invention provides a motor punching sheet of a heating compressor of a heat pump, a motor, and a compressor employing the motor. The punching sheet comprises a stator punching sheet and a rotor punching sheet, wherein the number of slots of the stator punching sheet is M and the number of slots of the rotor punching sheet is N. moreover, the number of slots of the stator punching sheet and the number of slots of the rotor punching sheet meet a formula: M=N+k, wherein k is an even number which is not less than 2. The specific setting of the number of slots of the stator punching sheet and the number of slots of the rotor punching sheet enables the yoke part and tooth part of the motor to be uniform in size, thereby guaranteeing the relatively uniform flux density, and avoiding the saturation of the flux density of an iron core. The motor punching sheet meets the requirements of big-torque operation of the motor.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a heat pump heating compressor motor plate, a motor and a compressor. Background technique [0002] With the improvement of people's awareness of environmental protection, for the heating of coal stoves commonly used in winter heating, because the exhaust gas produced by it is one of the factors that cause smog, in order to effectively improve air quality, there is an urgent need for more environmentally friendly heat pump heating equipment. Replace the existing coal stove for heating. [0003] Most of the existing heat pump heating equipment still uses ordinary air-conditioning compressors. However, such ordinary air-conditioning compressors cannot adapt to low ambient temperature, high outlet water temperature, high load pressure, high energy efficiency requirements, and long running time during use. Due to long-term use conditions, the motor is prone to overheating and bu...
