What is Shaft Voltage Testing?

Electric motors are a critical part of your Glendale, AZ, home's air conditioner, swimming pool pump, generator, exhaust fans, and other heating, ventilation, and air conditioning systems. Stray voltage in the shaft of the motor could cause a disruption to the system's functioning. At Run 'Em Again Motors, our Glendale-area technicians offer these three explanations for shaft voltage testing so that you can make an informed decision about system repairs and replacements.

1. What Shaft Voltage Testing Means

Shaft voltage testing is a measurement of how much voltage is leaking from the windings of a motor. It also measures whether or not the motor's voltage capacity has decreased for some reason, such as a loss of lubricant or insulation on wiring. This needs to be done if a motor has suddenly stopped or if there was a premature bearing failure.

2. How Shaft Voltage Testing Works

To perform shaft voltage testing, our technicians use a probe. The probe has a conductive brush at one end. The shaft voltage can be measured either at the driving end or at the non-driving end of the motor. The reference contact of the probe connects with the grounding wire of the motor's housing.

3. Why Shaft Voltage Testing Is Important

If there's too much voltage leaking out of an electric motor, this could lead to performance problems and a loss of efficiency. The bearings could fail, leading to excess wear and tear on the motor and extra repairs. If it continues, the entire motor could fail several years before the end of its average lifespan.
