How to Test a Motor
If your business operates in the wastewater, steel, automotive or power generation industries, you are familiar with electric motors. These devices work to keep manufacturing efforts and production processes in order by converting inputs into mechanical power. Electric motor systems contain dozens if not hundreds of parts vital for function, so preventative measures ensure your daily responsibilities can continue.
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 errors can happen when your team least expects it, so ALL-TEST Pro provides hand-held solutions for testing key motor components.
Motor Testing Importance
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. Don’t leave motor failure up to chance – reap the cost-saving benefits of complete motor testing.
Benefits of Electric Motor Testing
Electric motor testing is an effective route for understanding the condition of your machines. Resources such as the ALL-TEST PRO 7™ give you an accurate view of the motor’s health and pinpoints developing winding faults before they go to ground. Traditional tools are unable to detect small developing winding faults, but our devices give you complete and accurate information of the winding insulation, winding insulation to ground, and rotor.
Fault examples include:
- Developing winding faults (turn to turn, coil to coil, phase to phase)
- Ground faults
Motor testing products from ALL-TEST Pro are designed to give you readings in just minutes, allowing you to improve safety, enhance energy efficiency and save money on costly repairs. Equipment operators and managers can attach devices near controllers, fuse boxes and more to determine if a problem is present.
The process for testing a motor depends on if you need a deenergized (MCA™) or an energized (ESA) approach.
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.
