Large Motor Load Testing

Why load test your motor or generator? Bradleys’ recommends load testing to ensure reliability, to validate repairs, to verify performance, to ensure system compatibility between motors and drives, and prior to storage of your critical spare motors.

Bradleys’ large motor load testing capabilities are well known in the industry. Precision torque measurements and power input measurements assess your electric motor’s performance. Bradleys’ state of the art, in-house load testing control room offers remote monitoring of live data collection and live video stream. Your load test is managed by Electrical and Mechanical engineers and experienced load testing staff experts.

Our dynamometer has a torque measurement device capable of measuring 38,000 FT. LBS at 3600 RPM with a.1% accuracy on a motor load test.The dynamometer set up has several available combinations of speed and horsepower. We can perform a motor load test up to 7000 horsepower AC or 4500 AMP, 750V for DC motors. Data collection includes 12 temperatures, power, HP, efficiency, power factor, torque, speed, currents, and voltages. Data acquisition equipment calibrated within ISO 17025 standard.
