SAKOR Technologies Inc., a recognized leader in the area of high-performance dynamometer

systems, announces that it recently provided a dynamometer test system to General Atomics
Aeronautical Systems, Inc. for use in testing starters/alternators for military remotely piloted aircraft (RPA) of the Predator class and larger. The system features a 58 horsepower (Hp) AccuDyne™ AC 4 quadrant motoring dynamometer and other subsystems configured for starter/generator testing and is automated by SAKOR's DynoLAB™ test automation controller.

The SAKOR test system will be used by General Atomics Aeronautical Systems for testing the motor that starts the RPA turbines. Once under turbine power, this motor then turns into a generator that produces electricity for flight controls and sensor suite onboard the RPA.

The AccuDyne™ four-quadrant dynamometer is capable of full bi-directional braking or driving the
device under test. It can also provide full rated torque at stall (zero RPM). The dynamometer has
been configured with 58 Hp bi-directional motoring and absorbing; line-regenerative power
absorption; and a maximum speed of 12,600 rpm. The system is equipped with a heavy-duty test
bench; vertical rack enclosure; and a four-phase power analyzer configured to measure the DC input and three-phase AC voltage, current and power output from the DUT motor controller (inverter). SAKOR also provided on-site installation supervision, commissioning, and training services.

The system is automated by SAKOR's DynoLAB™ test automation controller, a powerful system
that enables test engineers and/or technicians to design and implement complex test procedures
without the need to learn a programming language. Operators can quickly configure and run tests
using the easy to use, menu driven interface.

"We are proud to be involved with the effort to provide our military with the most advanced
equipment in the world," said Randal Beattie, president of SAKOR. "RPAs are at the forefront of
modern technology and this test equipment will help ensure it remains state of the art far into the
