MagniX revs up electric motor to get set for flight

The Magni500 sounds just about as loud as you’d expect for an airplane engine — but technically speaking, this is no engine. It’s a 750-horsepower, all-electric motor that MagniX has been revving up to turn an aircraft propeller at full power.

That’s a significant milestone for MagniX, which has offices in Redmond, Wash., and in Australia. The successful ground tests signal that the company is getting closer to having the Magni500 flight-tested on a Harbour Air plane in British Columbia.

“This milestone is significant not only for MagniX, but for the electric aviation industry in general, because it is now the world’s largest all-electric motor (560 kw /  750HP) that has been installed in an aircraft-like system, turning a real full-sized aircraft propeller and controlling prop pitch via a governor,” MagniX CEO Roei Ganzarski told GeekWire in an email.

“This was the last step before installing such a system on an aircraft — in our case, the Harbour Air Beaver,” he said. “We are now testing our third 750HP motor.”

Ganzarski said MagniX has completed more than 50 hours of multiple full-power, full-flight profile tests on the Magni500 at its engineering center on Australia’s Gold Coast. “The motor has shipped to B.C. and has now been installed on the Beaver aircraft as part of the full system integration,” he said.
