Abstract

This application is applicable to the technical field of motor drive control, and provides a motor function safety control method and device. The method includes: obtaining the control command data sent by the host computer; obtaining the operation data of the motor; calculating the operation data to obtain the motor safety Running data; compare the size of the control command data and the safe running data; if the control command data is less than or equal to the safe running data, send the control command data to the motor controller, and control the motor controller to drive the motor to run according to the control command data. This application realizes the control of the current or power of the motor, ensuring that the actual temperature value of the motor is not greater than the temperature limit value, and can maximize the overload performance of the motor, and at the same time increases the rotation speed of the motor system through motor overload moment density.

Description

technical field [0001] The present application belongs to the technical field of motor drive control, and in particular relates to a motor function safety control method and device. Background technique [0002] In recent years, due to factors such as simple manufacture and low cost, motors have been used in various fields of equipment. [0003] The rated current or power of the existing servo motor or power motor refers to the current or power corresponding to the long-term operation of the motor when the temperature of the motor is below the limit value. [0004] However, in actual use, due to various factors such as the operating environment temperature, motor start-stop frequency, and full-load running time of the motor, the actual rated operating current and torque values ​​​​of the motor will vary according to specific applications. [0005] If there is a large margin in the rated operating current and torque of the motor, the volume and weight of the motor will be re...
