Super high speed permanent magnet synchronous motor monitoring system based on multi-sensor information fusion

Abstract

The invention provides a super high speed permanent magnet synchronous motor monitoring system based on multi-sensor information fusion. The monitoring object includes a super high speed permanent magnet synchronous motor and mains three-phase alternating current. The monitoring system comprises a monitoring device and a monitoring data receiving device. The monitoring device comprises a current sensor, a voltage sensor, a temperature sensor, a data acquisition card, a vibration sensor, a pickup, an upper computer and a display. The monitoring data receiving device comprises a drive and isolation module and an upper computer in a super high speed permanent magnet synchronous motor drive control system. The monitoring system can monitor the operation of the motor in various aspects and timely transmit the working condition of the motor to an upper computer operator. In the case of an emergency which may lead to an accident, the monitoring system can judge a fault according to detected data and take safe treatment measures.

AI Technical Summary

Benefits of technology

This patented technology allows for accurate detection of any problems caused by high speeds during operation without requiring human interference. It uses multiple sensors attached at different locations along its shaft to continuously measure various parameters such as temperature, pressure, vibration levels, etc., which helps identify issues early enough before they become critical. By analyzing these measurements over time, engineers are able to quickly respond accordingly while managing safety concerns effectively.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the security measures used during testing (“Safety Accident”) on high speed machines such as UHSPMs that can cause damage if they fail due to incorrect driving methods like faulty power supply.
