787 Starter‐Generator Test Stand



Max RPM: 9,000 RPM
Max Torque: 2,000 FT‐LBS
Max Power: 1,500 HP

This test stand is used by a major aircraft component manufacturer to simulate the power and quick acceleration generated by commercial airline starter‐generators. The first generation of these test stands was built in 2004 in a batch of four systems. Those four systems are still in operation and have been running 24/7 since they were commissioned; only being turned off for scheduled maintenance. This test stand showcases our tandem motor configuration design, where two motors are coupled together to allow for double the torque at a given speed. The fluid recirculating system is integrated into the 4 ton cast base.
