YOU CALL, WE HAUL
The load test center consists of a 1500 kva power supply, a motor efficiency panel, and an AW-900 and AW-600 water-cooled hydraulic dynamometer. Testing electric motors for operational efficiency and ability to create rated horsepower at rated speed within the electrical ratings of the motor is paramount to certified operational integrity.
Using a kilowatt meter, at any percentage of load on the motor, the efficiency of the motor can be determined. One horsepower is the equivalent of 746 watts. Using this factor and recording the wattage draw at any given horsepower, the efficiency of the motor can be calculated.
A dynamometer is a device used for measuring rotational force or power, and is used specifically to test motors under conditions of mechanical load. The mechanical force of rotation (torque) is measured by a load cell transducer in the dynamometer and is expressed in foot/pounds. A transducer transforms a mechanical signal into an electrical one. The rotational speed in RPMs is measured in the dynamometer by an electronic tachometer. Data from these two measurements during a motor test is fed into a computer, which calculates the horsepower produced by the motor at various load values. The dynamometer is capable of handling 20 HP through 900 HP with a 3200 ft/lb. rated torque shaft.
