Abstract

The invention relates to a motor temperature detection technique and discloses a method of detecting the temperature of the winding of a motor. The objective of the invention is to solve the problem of low temperature accuracy of a method in the prior art according to which a temperature sensor is adopted detect the temperature of a motor in an apparatus comprising the motor. The method of the invention includes the following steps that: at least one change rate in an apparatus comprising the motor is determined, wherein the at least one change rate includes a magnetic flux change rate and / or a resistance change rate corresponding to the motor; and the operating temperature of the motor is determined based on the at least one change rate. In addition, the present invention is provided with an apparatus comprising a motor. According to the method for detecting the temperature of the winding of the motor and the apparatus comprising the motor of the invention, the temperature of the interior of the motor is determined according to the magnetic flux change rate and the resistance change rate, and a test result is more accurate relative to a test result obtained through the temperature sensor; and since the temperature sensor is not required to be adopted, the cost of the apparatus comprising the motor is decreased.

Description

technical field [0001] The invention relates to motor temperature detection technology, in particular to a method for detecting motor winding temperature and equipment including the motor. Background technique [0002] With the advancement of science and technology, more and more electronic products have entered people's daily life, improving people's quality of life. Among them, the air conditioner is a device capable of adjusting the temperature, purity, and air velocity of the air in a closed space. The air conditioner sucks low-temperature and low-pressure refrigerant gas from the suction pipe through the compressor, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. [0003] When the compressor motor is working, the high current passes through to make the motor itself heat continuously, and the heat dissipation of the mot...
