QinetiX GmbH<\/a> in Germany manufactures a motor and controller combined in one case to lower weight and simplify installation.\u00a0 Their QPD-40, shown at the Aero Friedrichshafen E-Flight Expo and on their web page, seems to exemplify those goals.\u00a0 Its 12 kilogram (26.4 pound) weight and 40 kilowatt (53.6 hp.) output gives it a power-to-weight ratio of 3.2 kilowatts per kilogram (2 horsepower per pound).<\/p>\n

QuinetiX power system combines motor, controller in one case<\/p><\/div>\n

Running on 60 Volts at a maximum 680 Amperes, the motor produces 212 Newton-meters (156.4 foot-pounds) of torque, swinging a propeller at only 1,800 rpm, allowing for quiet operation. \u00a0The liquid-cooled stator and power electronics will require some form of heat exchanger, but probably with fairly low cooling drag overall.<\/p>\n

Only 90 millimeters (3.54 inches) thick and around a foot in diameter, the motor should fit neatly into streamlined propeller spinners.\u00a0 Other uses in automobiles and wind turbines present hopeful potential applications for this neatly-packaged motor.<\/p>\n
