Embodiment Construction

[0046] figure 1 A schematic illustration of an electric motor 1 is shown. The motor 1 is fixed on the bracket 6 . The electric motor 1 comprises a shaft 9 , a motor bearing housing A side 4 and a motor bearing housing B side 5 , which enclose the motor housing of the electric motor 7 . The motor bearing housings 4 , 5 form the front and rear covers of the motor housing 7 . The motor interior is protected from contact by the motor bearing housings 4 , 5 which accommodate the bearings of the shaft 9 . The A side 4 of the motor bearing housing is referred to as the drive side and usually supports a single-piece bearing. The B-side 5 of the motor bearing housing is the "fan tray" and is usually mounted via slide mounts. Furthermore, the electric machine 1 has a switch box 2 . The switch box 2 is fixedly connected with the motor 1 . Via the connection opening 8 of the switch box 2 , the motor connection line can be connected to the electric motor 1 for supplying energy. The ...

Abstract

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.

Description

technical field [0001] The present invention relates to a condition monitoring system for electric motors. Background technique [0002] The provision of condition monitoring functions for plants and especially electric motors is often accompanied by expensive installation outlays. In particular, the subsequent provision of a condition monitoring function for the electric machine is often cumbersome and may require structural measures. The sensors required for monitoring must be positioned and mounted on the motor. In addition, the sensor must be wired to the control it is attached to. Freely arranged lines in the working space must be provided, for example, by means of paths or underfloor cable channels, in order to prevent danger to persons and machines in the working area. Due to the additional installation of sensors and the additional arrangement of lines, it may be necessary to reassess the safety of the installation. [0003] During retrofitting, the sensors requi...
