AC Dynamometers

Foot mounted, blower cooled, and dual ended, with scalable inline torque transducer. Shaft lock mechansim for dead weight calibration.

36 Hp Regenerative AC Transient Dynamometer including AC power electronics, dynamometer controller & safety monitoring. The foot-mounted, blower cooled, AC Transient dynamometer is rated at 36 Hp absorbing from 2000 RPM to 3400 RPM with a decreasing horse power range from 3400 RPM to 6000 RPM. The high-torque design allows testing at low-speed, high torque, while offering acceleration and deceleration at the transient ranges with extremely accurate low or high load stability for steady state testing. Mounted on plate to allow vertical mounting when needed.

Trunnion mounted, blower cooled, with traditional load cell. Single ended, configured for optional inline torque transducer. Constant Torque (absorbing): 1750 ft-lb through speed range 0 to 1200 RPM; max speed 4,000 RPM

30 HP and 250 HP water cooled AC dynamometers in test stand that tests a family of 14 air starters. Three variable-speed outputs, maximum speeds of 10,000 - 20,000 - 31,000 RPM. Integrated telemetry-type torque sensor.

Electro-mechanically actuated variable height table for electric motor testing application. Speed up to 6,000 RPM with constant torque of 120 lb-ft up to 2,200 RPM.

Foot mounted, blower cooled AC dynamometer with inline torque transducer and shaft lock. 15HP with speeds up to 7,000 RPM. Highly accurate, telemetry type torque measurement.

600 HP, single-ended, with inline torque transducer. Blower cooled with winding heaters for high humidity testing environments.

5 HP high speed table-mounted horizontal test stand. Totally enclosed, non-vented with reactionary load cell. Max speed is 15,000 RPM.

75 HP chassis dynamometer. Right angle gearbox and inline torque sensor that allows torque measurement directly at the rolls.

Chassis dynamometer designed for golf cart testing application utilizes twin 50HP liquid cooled AC dynamometers with max speed of 9,000 RPM and constant torque range at 0-4500 RPM of 52.5 ft-lb (71Nm).

200 HP Trunnion mounted, liquid cooled with max speed 10,000 RPM.

Trunnion mounted, liquid cooled, and dual-ended AC dynamometer. Designed and built for diesel engine emissions testing.

Two 47 Hp, 2,000/6,000 RPM blower cooled, foot mounted AC dynamometers on a stationary table. One tests vertical shaft engines, and the other is horizontal. View 1, with engine's muffler removed.
