Condition monitoring system for a motor

摘要

In order to enable simple, low-cost monitoring of a motor, a switch box cover for the motor, a condition monitoring system has a sensor unit for detecting a measured variable of the motor, a communication device, which is designed to provide a characteristic value that characterizes the measured variable to a reading device, and a supply unit for supplying the sensor unit with energy.

主权项

1. A terminal box cover for a motor, comprising:
a sensor unit to record a measured variable for a condition of the motor, the measured variable including at least one of a temperature of the motor, a temperature of a stator winding of the motor, and an out-of-balance condition of the motor; a communications device to transmit to a reading device a parameter that characterizes the measured variable available; and a supply unit to supply energy to the sensor unit, the supply unit being supplied with energy from an energy source that is external to the terminal box cover, wherein all components of at least the sensor unit and the communications device are provided completely within the terminal box cover, which fits on and covers a terminal box, the terminal box is fixed to the motor, and the terminal box cover forms a self-sufficient monitoring unit for monitoring the condition of the motor.
