Sakor Technologies' VersaDyne is an integrated system for testing two- and four-cycle engines found in small outboard motors, motorcycles, tractors, lawn care tools, and generators. Available in sizes from 5 to 30 kW (7 to 40 hp), the VersaDyne features a regenerative ac motoring dynamometer in a convertible, horizontal/vertical package. Flux Vector technology offers a range of speed and torque control and can test engines over various performance characteristics. A regenerative design returns absorbed power to the plant mains, minimizing heat rejection and external cooling. Motoring capability provides automatic engine starting and testing of transient engine loads. A DynoLAB controller offers automated test cycle control in a Windows-based environment, and the expandable I/O system completes data acquisition in a single package.
