Why Test Motors?

Motor Testing Importance

Don’t Let Business Operations Stall

Many industries, including wastewater, steel, automotive or power generation industries, use electric motors to sustain production processes by converting inputs into mechanical power. Electric motor systems contain dozens if not hundreds of parts vital for business operation, so preventative measures are necessary to ensure your daily responsibilities continue.

Motor Testing Importance

Professionals often think if a motor sounds like it’s working, then systems must be in order. However, this assumption is far from the truth. Motor failures can happen when your team least expects it.

In addition, not all winding faults start as ground faults. Instead, they can start as a weakness in the winding insulation system that may eventually fault to ground when the motor stops running.

Motor testing is integral to the success and efficiency of your business. ALL-TEST Pro instruments ensure that testing your motor is safe, easy, and dependable. Our capabilities for troubleshooting and predictive maintenance are a means of sustaining critical systems and achieving meaningful ROI.

ALL-TEST Pro provides hand-held diagnostic devices for testing key motor components.

Why Traditional Megohmmeter Testing Isn’t Enough

Megohmmeter insulation testing only detects faults to ground. Since only a portion of motor electrical winding failures begin as ground faults, they will go undetected using this method alone. Moreover, surge testing requires the application of high voltages. This can be destructive when testing a motor, making it an unsuitable method for troubleshooting and true predictive maintenance testing.

ALL-TEST Pro devices offer more complete motor testing than any other options on the market. Our instruments go above and beyond normal testing equipment for accurate, safe, and fast motor testing. Motor testing using an MCA™ tool is very easy to implement, and the test takes less than three minutes. Save money and time by proactively detecting developing faults before they cause irreversible motor failures.

Benefits of ALL-TEST Pro Devices

While traditional tools, such as a megohmmeter, are unable to detect small developing winding faults, our devices, such as the ALL-TEST PRO 7™, provide comprehensive, accurate information of the winding insulation, winding insulation to ground, and rotor.

Benefits include:

  • Hand-held (usable in any environment)
  • Provide 6+ Diagnostic Readouts (opposed to current Megohmmeters with only 1)
  • Easy to Operate
  • Responsive Customer Support

Deenergized (MCA) vs Energized (ESA)

MCA™ Deenergized Testing

MCA™ is a non-destructive deenergized test method to assess the health of a motor from the Motor Control Center (MCC) or directly at the motor, providing immediate and complete information on the status of the stator, rotor, connections, contamination, and insulation to ground.

ESA Energized Testing

Electrical Signature Analysis (ESA) is an energized test method where voltage and current waveforms are captured while the motor system is running, providing valuable information for AC induction and DC motors, generators, wound rotor motors, synchronous motors, machine tool motors, and more.
