The transmission being tested is driven by a 15HP motor controlled by a variable speed vector drive. The motor is mounted in a cage supported by aircraft roller bearings. A strain gauge measures the torque reaction on the motor cage.
This allows us to measure the actual torque needed to spin the transmission. By using a digital tachometer  we can calculate the actual HP required at any given RPM.
