Motor Current Signature Analysis (MCSA)



providing access to
critical data

The addition of Motor Current Signature Analysis (MCSA) to KCF’s comprehensive machine health platform combines MCSA’s robust motor-electrical diagnostic capabilities with the high-fidelity continuous monitoring, ease of installation, and focus on root cause eradication that are central to KCF’s solutions. Pairing this technology with vibration monitoring results in a comprehensive asset health solution crafted for your most critical electric motors.

Additional Operating Data Uses Unlocked
by MCSA in KCF’s Machine Health Platform:

  • Power Consumption
  • Power Factor Duty Cycle (+ total operating hours)
  • Motor Efficiency

Motor Current Signature Analysis (MCSA)

When should you use MCSA?

1. Costs of Downtime Are High

When failure costs a significant sum due to lost production.

2. Failure Prevention is Essential

When motor replacement cost is significant, or failure results in collateral damage such as product needing to be discarded, or adjacent equipment being damaged.

3. Regulatory & Fines Risk Reduction

When catastrophic failure results in fines levied against the customer

Motor Current Signature Analysis MCSA software and hardware

Our MCSA Solution Unlocks

24/7 Monitoring

Provides continuous online monitoring with 24/7 access to critical data. Effectively covering all blind spots that exist between readings in periodic route-based monitoring.


Allows motor behavior during start up to be trended over time, enabling early detection of damaging conditions and motor issues.

Improved Safety

Route-based analysts or
maintenance staff members no longer need to enter dangerous environments to take readings.

Root Cause Analysis

The inclusion of potential
transformers facilitates power supply monitoring. This enables the identification of chronic power supply issues, eliminating the cause of motor faults and suboptimal performance.

Motor Current Signature Analysis (MCSA) Hardware

Current Transformers (CTs):

Detects motor faults.

Current Triggering

Enables synchronized sampling on motor startup, enabling the identification of hard to catch phenomena including inrush current.


Provides precise reading of motor (rotor) turning speed—important for MCSA Analytics Model.

Potential Transformers (PTs):

Enables electrical current signature analysis (ESA). Identifies power supply issues and enables root cause analysis.

KCF’s MCSA solutions are possible with an IoT HUB and Analog Adapter. For more information, please reach out to the KCF Technologies Team!
