SERVICE

Did you know Yellotec now offers advanced de-energized diagnostic services for electrical motors? Using innovative technology from ALL-Test Pro, we can take measurements from Motor Control Centers (MCCs), isolators, contactors, and Variable Frequency Drives (VFDs).  

Key Diagnostic Measurements: 

  • Winding Resistance 
  • Impedance 
  • Inductance 
  • Capacitance 
  • Dissipation Factor 
  • Phase Angle 
  • Current Frequency Response 
  • Insulation Resistance 

 

Detected Failure Modes: 

  • Turn-to-Turn, Coil-to-Coil, and Phase-to-Phase Faults 
  • Insulation Failures 
  • Open Phases 
  • Burned or Contaminated Windings 
  • Poor Connections 
  • Broken or Cracked Rotor Bars 
  • Rotor Casting Voids 
  • Rotor Eccentricity 
  • Grounded Windings 
  • Cable Faults 

 

Recommendations:
Perform Motor Circuit Analysis (MCA) every 6-12 months for: 

  • Critical motors in use 
  • Spare motors in storage 
  • Motors that frequently stop/start 
  • Motors in harsh environments 
  • Motors with known issues 

 

MCA is Non-Destructive, Versatile, and Fast.  Suitable for AC induction, DC, Synchronous motors, Generators, and Transformers. Experience Yellotec’s reliable testing services to ensure optimal motor performance. Contact us for more information or to schedule a consultation.

PRODUCTS
for Electric Motor Testing

 DE-ENERGIZED (MCA™) TESTING

Motor Circuit Analysis (MCA™) enables de-energized motor testing of the entire electrical portion of the motor system. Our product lineup for this category includes the highly popular: ALL-TEST PRO 7™ PROFESSIONAL, ALL-TEST PRO 34™, ALL-TEST PRO 34 EV™, and MOTOR GENIE®.

ENERGIZED (ESA) TESTING

Electrical Signature Analysis (ESA) is an energized test method where voltage and current waveforms are captured while the motor system is running, allowing for a comprehensive assessment of the motor system’s health. In this category, you can choose from our: ALL-TEST PRO On-Line III™ and the ALL-SAFE PRO®, an accessory to the ATPOL III™.

ASSEMBLIES

Our assemblies integrate ESA, MCA, and software to enhance plant productivity, offering a rapid return on investment (ROI). For comprehensive motor analysis, we provide the:ALL-TEST PRO MD III™ assembly.
