Problems solved by technology

The conventional protection method sets a fixed temperature protection threshold according to the worst working conditions. When the motor and power module exceed the temperature protection threshold, the motor driver will immediately stop the drive output, but this may bring frequent protection shutdowns, causing users Poor app experience

Abstract

The present invention proposes a motor control method, device and electrical equipment, wherein the method includes the following steps: acquiring temperature parameters and power parameters when the motor is running; judging whether the temperature parameters are greater than the corresponding temperature protection limit, whether the power parameters are greater than the corresponding The power protection limit; when the temperature parameter is greater than the corresponding temperature protection limit, and / or, the power parameter is greater than the corresponding power protection limit, according to the difference between the temperature parameter and the corresponding temperature protection limit, and / or Or, the difference between the power parameter and the corresponding power protection limit value is adjusted to the preset current limit value to obtain the current adjustment value; the motor is controlled according to the current adjustment value. Therefore, when the temperature of the motor, the temperature of the power device, the input power of the motor or the motor driver exceeds their corresponding protection limits, the current derating can be performed, the maximum current output capability of the driver can be reduced, and the shutdown can be reduced or avoided, taking into account the user experience and safe.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a motor control method, a motor control device, a computer-readable storage medium and an electrical device. Background technique [0002] AC motor drive systems are widely used in household appliances, industry, automobiles and other fields. In order to prevent the motor and driver from being damaged under heavy load, it is usually necessary to protect the motor body and the driver power module from overheating. The conventional protection method sets a fixed temperature protection threshold according to the worst working conditions. When the motor and power module exceed the temperature protection threshold, the motor driver will immediately stop the drive output, but this may bring frequent protection shutdowns, causing users Bring poor application experience. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the ...
