Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an online motor fault monitoring device. Background Technology

[0002] An online motor is a type of motor that can be networked with an external system through built-in or external sensors, data acquisition units, communication modules, and other technical means. When a fault occurs in the motor, the vibration produced can be compared with that produced by a standard motor. Fault monitoring devices are usually used to monitor the motor for faults.

[0003] When monitoring a motor for faults, the operator needs to place the motor on the monitoring plate and start the motor to rotate. The motor drives the monitoring plate to vibrate, and the monitoring plate moves via a moving block. The displacement sensor senses the distance the moving plate moves and transmits the data to the processing device. The processing device compares the displacement data with the displacement data of a standard motor during vibration and displays it.

[0004] Because the monitoring board cannot limit and fix the motor during motor fault monitoring, there is a situation where the motor and the monitoring board vibrate asynchronously when the motor drives the monitoring board to vibrate, which reduces the monitoring effect of the fault monitoring device on the motor. There is an urgent need to design an online motor fault monitoring device to solve the above problems. Utility Model Content
