MCMSoC (MCM System On a Card) MCM (Motor Condition Monitor) is one of Artesis award-winning products, 40 Best products of 2000, Control Engineering Magazine, USA. MCMSoC (a predictive fault sensor) provides embedded condition monitoring solutions to assure early warning of faults and prevent unexpected breakdowns in OEM (Original Equipment Manufacturer) products and systems.
MCMSoC (Predictive Fault Sensor) What is MCMSoC (predictive fault sensor)? MCMSoc is a coprocessor/add-on unit for mounting in the control/monitoring system of an OEM product MCMSoC is customized to the requirements of each user MCMSoC is intended for volume applications and as such will have considerable cost advantages MCM is used for preventative maintenance by end users MCMSoC is for OEM producers interested in applying condition monitoring to their own equipment
MCM: Key Advantages Benefits of MCM and MCMSoC Increases Efficiency Reduces Expenses Increases Plant Value Increases productivity and decreases the cost of repair by early warning of pending breakdowns. Decreases the cost of energy and production losses by process optimization. Increases the efficiency and quality of production by remote monitoring machines and related equipment. Increases the life of machine and related equipment and the plant value by finding out the root causes of failure. Increases the effectiveness of maintenance staff.

Principles of Model BasedB Fault Detection (1) Machine Profile Change in Profile Fault Warning Diagnosis u System (realized) Model Model Θ (estimated) y s y m Σ Σ e = y s -y m MCM determines the model and profile (parameters) of electr motor-based systems under normal operating conditions. These parameters are then used to estimate the system outp If the system outputs do not fit with the estimated values, then gives warning. The faults are identified by examining the differences in the system profile.
Principles of Model BasedB Fault Detection (2) MCM must handle conditions of variable input voltage, frequency and load, represented here as a surface in a multi-dimensional space. MCM learns the shape of this surface prior to starting system monitoring properly and finds the model parameter values at each point on a grid over the surface. During monitoring MCM will update this information if it finds a new position on the surface. Fault severity is determined by the difference between the measured parameters and those previously learned.
How MCM Finds Mechanical Faults by Using Only Currents and Voltages The relationship between input voltage and output current (characterised by the parameters) is very sensitive to air gap variations Any influence that causes the air gap to change can, (in principle) be detected by the effect it has on the parameters
MCM (Motor Condition Monitor) MCM monitors electric-motor based machines continuously measuring currents and voltages only. The measurements and results are stored in a database on a remote PC for remote monitoring and trend analysis. Early Fault Detection Diagnostics Energy Quality and Consumption Effectiveness of Maintenance Equipment Availability STOP PERFORM MAINTENANCE WATCH LOAD WATCH LINE OK MCM can be installed on motor control panels. MCM is easy to install
Benefits of MCM and MCMSoC In a Nutshell In a single, cost-effective unit that is simple to install and run, MCM / MCMSoC can provide: - Continuous and automatic monitoring of electrical and mechanical fault conditions with operator action required only as a fault develops - Maintenance scheduling by monitoring the severity of a fault as indicated by the rate of deterioration - Energy monitoring and harmonic analysis MCM / MCMSoC can be extended to other applications such as power transformers, rotating systems, gas turbines, wind turbines, generators, etc.
MCMSoC Integrated Intelligent Products
Detective Multimeter The firts integration of MCMSoC The Motor Condition Monitor (MCM) technology, which is being developed, manufactured and marketed by Artesis Techonology Systems, is integrated with a microprocessor based panel multimeter as a result of the collaboration between Inter Electric-Electronic and Artesis. This new product, called Dedective Multimeter is based on a new, state-of-the-art technology and it will lead other next generation products.
Applications of MCM Technology MCM is being used to monitor: Pumping systems (circulation, lubrication, hydraulic, filtration, fuel, water, gas etc) Compressors (refrigeration, gas,nitrogen and air etc.) Control panel of Compressors, Fans, Pums, Gear Boxes, Presses.. Industrial Machines: Paper, Textile, Glass, Plastic... Industrial Equipment :Powermeters, Multimeters, Digital Voltmeters, Invertors, Electronic Over Current Relays, Electronic Motor Protection Relays, Softstarters, Meetering & Monitoring Equipment, Air Circuit Breakers, Molded Case Circuit Breakers, Contactors, Energy Analyzers, etc. Medium & High Voltage applications: Motor Protection Relays- Softarters, Industrial Motors, Monitoring Equipment, etc.
MCMSoC (Predictive Fault Sensor) MCM is used for preventative maintenance by end users. For OEM producers interested in applying condition monitoring to their own equipment, MCMSoC should be considered MCMSoC is a coprocessor/add-on unit for mounting in the control/monitoring system of an OEM product MCMSoC is customized to the requirements of each user MCMSoC is intended for volume applications and as such will have considerable cost advantages
