How to Perform a Motor Solo Run Test Procedure - PDF Download
A motor solo run test procedure is a method of testing the performance and condition of an electric motor without connecting it to any load or equipment. It is also known as a no-load test or an open-circuit test. This test can help you identify any faults or defects in the motor, such as winding damage, insulation failure, bearing problems, or misalignment.
In this article, we will explain how to perform a motor solo run test procedure step by step, and provide you with a free PDF download of the test report template. You will also learn about the benefits and limitations of this test, and how to interpret the results.

A tachometer or a speed sensor to measure the motor speed
A multimeter or a clamp meter to measure the voltage and current of the motor
A power supply to provide the rated voltage and frequency to the motor
A thermometer or a thermal camera to measure the temperature of the motor
A sound level meter to measure the noise level of the motor
A vibration meter or an accelerometer to measure the vibration level of the motor
A stopwatch to measure the time duration of the test
A motor solo run test report template to record the data and observations
How to Perform a Motor Solo Run Test Procedure - Step by Step Guide
Follow these steps to perform a motor solo run test procedure:
Disconnect the motor from any load or equipment, and ensure that it is properly grounded and secured.
Connect the power supply to the motor terminals, and set it to provide the rated voltage and frequency of the motor.
Connect the tachometer or speed sensor to the motor shaft, and ensure that it is calibrated and accurate.
Connect the multimeter or clamp meter to the motor terminals, and set it to measure the voltage and current of the motor.
Connect the thermometer or thermal camera to the motor casing, and ensure that it is calibrated and accurate.
Connect the sound level meter to a suitable location near the motor, and ensure that it is calibrated and accurate.
Connect the vibration meter or accelerometer to the motor casing or shaft, and ensure that it is calibrated and accurate.
Start the power supply, and let the motor run for at least 15 minutes to reach its steady state condition.
Measure and record the following parameters at regular intervals (e.g., every 5 minutes):Motor speed
Motor voltage
Motor current
Motor temperature
Noise level
Vibration level
Stop the power supply, and let the motor cool down for at least 10 minutes.
