Design and development

The Power Drive 20 is part of a family of scalable electric motor designs produced by Yuneec. The Power Drive 20+ produces the same power but at a reduced rpm.[1]

The family of engines is designed to use the company's own power controller, Lithium polymer battery pack and charger, as an integrated package of components. This ensures that all components are compatible and also removes the need for aircraft builders to separately source components.[1][2]

The Power Drive 20 is a brushless 67 volt design producing 20 kW (27 hp), with an outrunner. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive.[1]

Variants
Power Drive 20
Model that produces 20 kW (27 hp) at 2400 rpm, with a weight of 8.2 kg (18.1 lb).[1]
Power Drive 20+
Model that produces 20 kW (27 hp) at 2000 rpm, with a weight of 9.8 kg (21.6 lb).[1]
