Motor life monitoring method and device

Abstract

The invention provides a motor life monitoring method and device. The motor life monitoring method includes the following steps: obtaining the current speed of the motor body; sending the current speed to the speed control module, so that the speed control module adjusts the speed of the motor body based on the current speed and the preset speed; The life estimation module realizes the monitoring of the life of the motor body based on the range of speed change. The invention can guarantee the motor speed, thereby ensuring the quality of processed products, avoiding the increase of product processing reject rate due to the change of motor speed, and eliminating the influence of motor resonance on product processing; by monitoring the life of the motor in real time, it can Before the motor reaches the life limit, the motor is replaced in time, which effectively avoids the impact of the damaged motor on the quality of the processed product, ensures the normal progress of the processing process, and solves the problem of interruption of the processing process caused by the life of the motor.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a method and device for monitoring the life of a motor. Background technique [0002] With the development of electric energy, electric energy plays an important role in people's production and life. From a small perspective, most equipment needs to be driven. At present, the most important driving method is to use motor drive. Therefore, the motor's Research comes into the spotlight. [0003] In the process of existing product processing, the speed of the motor will have a great impact on the quality of the product. For example, in the field of printing technology, when the printing work is carried out by the motor-driven printing device, the motor may vibrate due to external factors, which will affect the speed of the motor. Influence, especially during the working process of the motor, resonance may occur, causing the speed of the motor to change. If the speed of the motor is ...
