Monitoring and Diagnosis System for Rotating Machinery Using Motor Current 'T-MCMA'
Current signal measurement unit: (3CH) TMDU-C3B / (12CH) TMDU-C12B, diagnostic management software: TMDS-120
It is a diagnostic technology for equipment that can monitor and diagnose the condition of rotating machinery with "safety, accuracy, and simplicity," matching the era of smart safety and work style reform!
"T-MCMA" is a current information diagnostic system that enables remote monitoring and diagnosis of the condition of rotating machinery. By developing the technology of current signature analysis, it can detect not only motor anomalies but also mechanical abnormalities such as unbalance and misalignment, as well as electrical abnormalities like insulation degradation and inverter issues, and deterioration of power transmission components such as gears, belts, and chains. Eight types of diagnostic parameters are set, and the condition of the rotating machinery is evaluated based on the parameter values calculated for each measurement. 【Features】 ■ Applicable regardless of the environment at the installation site of the rotating machinery, as current is measured in the electrical room. ■ Capable of diagnosing the specifics of anomalies occurring in the target rotating machinery. ■ Quantitative evaluation of the degree of anomalies based on parameter values. ■ If an anomaly is detected, our staff can support the investigation of the cause upon request. ■ Continuous monitoring is possible as measurements are conducted automatically. ■ Applicable to a wide range of rotating machinery, including general rotating machinery, low-speed rotating machinery, and high-pressure motors. ■ We also offer the "TM-CLOUD" service, which utilizes "T-MCMA" through the cloud. *For more details, please feel free to contact us.

basic information
**Current Information Diagnosis** Current information diagnosis is a technology that analyzes and diagnoses the condition of rotating machinery based on current signature analysis. When an abnormal condition or change occurs in rotating machinery, it can cause imbalances in the magnetic gap, which in turn disturbs the magnetic field within the stator, resulting in a weak back electromotive force in the stator current of the induction motor. By analyzing the specific information of the induction motor stator current affected by this back electromotive force, it is possible to analyze and diagnose the condition of the rotating machinery. **TM-CLOUD** "TM-CLOUD" is a service that allows users to utilize "T-MCMA" through the cloud. As long as there is an internet connection, monitoring and diagnosing rotating machinery can be performed from anywhere. Customers using "TM-CLOUD" are provided with a viewing software service called "VFC-1." "VFC-1" is a web browser system that enhances the convenience of data viewing and includes features that support diagnosis, such as detecting abnormal signs through diagnostic assistance functions and automatically generating diagnostic reports. *For more details, please feel free to contact us.*
