Electric motors and mechanical systems are subject to deterioration and damage that can suspend operations, leading to expensive repair and downtime.


Framatome offers the Electric Motor Performance Analysis & Trending Hardware (EMPATHTM) system to conveniently measure and analyze electric motor current and voltage to obtain information on critical processes and equipment. EMPATH helps owners detect potential motor problems early, enabling timely repairs and avoiding serious damage.

The key to EMPATH’s successful track record is its utilization of Motor Current Signature Analysis (MCSA) technology.

The Theory of MCSA

When an electric motor drives a mechanical system, it experiences variations in load caused by gears, pulleys, friction, bearings, and other conditions that may change over the life of the motor. The variations in load caused by each of these factors in turn cause a variation in the current supplied to the motor. These variations modulate the carrier frequency.

EMPATH utilizes a unique process to demodulate the signal from the carrier and present an unambiguous spectral display. Using normal and demodulated data permits analysis of not only the motor but also the load and the supplied power.

The EMPATH System

The EMPATH system consists of a laptop computer with our exclusive signal conditioning board. Analysis software stores data and gives a readout of the time and frequency signatures. The signal conditioning board collects data on all three phases of voltage & current and provides MCSA-filtered signals. Also, two general-purpose input channels give the customer the option of collecting additional data simultaneously (such as vibrations, temperature, pressure, etc.).

Customer Benefits

  • EMPATH hardware is CE qualified.
  • EMPATH provides unique algorithms that can reliably detect the early stages of rotor bar failures in induction motors.
  • EMPATH saves time and precludes plant walkdowns by monitoring plant motors and driven machinery from a central motor control center.
  • Auxiliary channels allow acquisition and analysis of data from a variety of other sources such as accelerometers (vibration data collection), proximity probes or process measurements. This
    information, properly analyzed, can greatly enhance a predictive
    maintenance program.
  • The EMPATH System permits data
    acquisition and analysis of not only AC induction motors but also DC motors, synchronous motors, generators and transformers. Efficient energy utilization is also
    indicated by the EMPATH analysis

EMPATH Continuous
Monitoring System (ECMS)

Enhance your motor reliability
program while lowering testing costs



Electric motors and mechanical systems are subject to deterioration and damage that can impact operations, leading to expensive repairs and downtime. Electrical Signature Analysis (ESA) methodology is an additional tool to be used in the plant’s motor reliability maintenance program (RMP). The fully-automated, remotely-operated ECMS platform can improve motor testing efficiency and reduce the cost of current testing methods.


Framatome’s proven product, EMPATH, enables users to detect potential motor problems early, enabling timely repairs while avoiding serious damage. The EMPATH Continuous Monitoring System (ECMS) is designed to automatically test multiple motors from a remote location.

EMPATH Continuous Monitoring
System ECMS-32 & ECMS-E1

ECMS-32 hardware consists of a 32-channel multiplexer and signal conditioner. The inputs to ECMS-32 are provided by the E-Plug modules, which are permanently installed inside the Motor Control Centers (MCCs).

ECMS-E1 is single channel hardware, which includes a builtin E-Plug module. ECMS-E1 is designed to be permanently installed inside the MCCs.

ECMS systems automatically pulse motors at user-defined intervals, collect and analyze the data, and then store that data in various locations, including cloud servers. In cases where critical performance parameters are out of tolerance, ECMS will automatically flag those items and send notification via SMS, emails and on-screen indications. The acceptances/tolerances can be set by the operator or automatically using statistics created by collected data.

Customer Benefits

  • Detects stator defects including winding stresses, missing wedges, rotor defects such as broken rotor bars or wye rings, static and dynamic eccentricity, which identify driven equipment and alignment faults, bearing defects, coupling faults, fans/pumps/gearbox/belt issues
  • Detects issues in AC/DC motors, AC/DC generators, machine tool and robot motors and steppers, VFD, transformers, hybrid vehicles, wind generation and powertrain, DC drives, and more
  • Sends warnings and alarms via email, SMS, or other conditions and can be linked to SCADA, PI and similar systems for inclusion in complete solutions
  • Automatically test multiple motors from a remote location
  • Detects on and off-shore wind turbine control, transformer, generator, gearbox, main bearing and blade defects automatically
