Artesis MCM Data sheet

PS.01 KT.08 REV:04

Motor Condition Monitor for Fixed Speed Motors

Artesis MCM Line

Description

MCM continuously identifies existing and developing faults on electric motors and
their driven equipment. MCM utilizes an intelligent, model-based approach to
provide anomaly detection by measuring the current and voltage signals from the
electrical supply to the motor. It is permanently mounted, generally in the motor
control center and is applicable to 3-phase AC, induction or synchronous, fixed
speed motors. Accompanying MCMScada Software or Artesis Enterprise Server
(OPC Server) is used to view the data.

MCM provides both mechanical (unbalance, misalignment, roller bearings, etc.)
and electrical (loose windings, short circuits, etc.) anomaly detection as well as
electrical parameters such as voltage and current imbalances and power factor. In
addition, it can detect changes in the load the motor is experiencing due to
anomalies in the driven equipment or process such as cavitations or plugged filters
and screens. Since it doesn't require any sensor installation on the motor itself or
associated load, MCM is especially attractive for inaccessible driven equipment
and is applicable to most types of pumps, compressors, and similar loads.

GENERAL INFORMATION

Motor Type

3-phase, AC (not suitable for DC motors), fixed speed (line driven) motors.
Motor current (load) variation must be less than 15% during 6 sec data acquisition
period. Not for use with soft-starter systems unless they are automatically
bypassed immediately after motor start-up and during subsequent use
