Electronic Motor Manager improves predictive maintenance

Phoenix Contact’s new Contactron Electronic Motor Manager (EMM) precisely monitors the effective power consumed by motors. The EMM uses this data to analyze errors and provide early warning to the controller, helping to increase system availability.

The EMM converts the motor itself into a sensor. The user can set the parameters to detect dangerous operational conditions, such as overload, underload, pollution and wear. The module provides advanced diagnostics and allows the user to make informed decisions for predictive maintenance and better operation. In a worst case scenario, the EMM can shut down the motor to protect the system.

For example, the EMM could detect a clogged filter in a pump, preventing dangerous dry running conditions.

The EMM’s onboard inputs and outputs facilitate direct control of motor starters. It provides easy-to-understand remote indication of system problems. The 22.5-mm module has selectable tripping curves of class 10 to class 30, for full three-phase motor protection. Up to 16 EMMs can be controlled with a single Profibus gateway, reducing costs, space and wiring time.
