Online Motor Testing

Maximizes the Dependability of Motors, Generators, and Transformers

Our experienced technicians use innovative technology for online monitoring of power circuit issues and overall motor health, load, and performance, giving you a comprehensive look at the overall integrity of your motor.


Using the online motor-testing equipment, L&S Electric provides root-cause analysis by separating the mechanical and electrical issues. Along with any three-phase induction motor, it will also monitor the activities of Variable Frequency Drive (VFD) applications.


L&S Electric’s on-line capabilities create an accurate assessment of operating load conditions over time. Results are immediate and show operating efficiencies allowing you to determine the true cost of wasted energy.


Comprehensive Motor Analysis

  • Identifies possible power circuit problems that degrade motor health
  • Examines overall motor power conditions
  • Monitors the load and observes motor performance
  • Estimates energy savings

VFD Monitoring

  • Shows how frequency, speed, torque, and voltage level vary with respect to time
  • Enables identification of transient overloading of the motor by the VFD
  • Provides the ability to identify and repair poorly tuned speed feedback

Advanced Data Collection

  • Saves individual motor results, critical for any predictive maintenance program
  • Generates reports quickly and easily
