Temperature equalization control method and device for motor

Abstract

The embodiment of the invention provides a temperature equalization control method and device for a motor. The method comprises the following steps: acquiring parameter information of an evaporation pipeline and frequency information of a booster pump; the parameter information comprises at least two of temperature information, pressure information, flow information and a medium evaporation point position; determining a parameter difference objective function according to parameter information and the frequency information; determining frequency control information of the booster pump according to the minimum value of the parameter difference objective function; adjusting the execution target frequency of the booster pump according to the frequency control information; the target frequency is used for adjusting the rotating speed of the booster pump to adjust parameter information of the evaporation pipeline. According to the technical scheme provided by the embodiment of the invention, the temperatures of different areas of the stator are uniform, the temperature difference between different areas of the stator is reduced, the thermal stress of the stator is reduced, the overall temperature uniformity of the motor is improved, and the stator silicon steel sheets of the motor are prevented from warping to damage insulation.
