JEDRILICA ANTARES 20E

ELEKTRICNA JEDRILICA sa trofaznim elektricnim motorom.

Fixed-shaft electric motor running on DC-DC current. Running at 190 - 288V, and pulling up to 160A, the 42kW / 57 hp motor can deliver maximum torque over a wide RPM range. With a total efficiency of 90% and a maximum torque of 216 Nm, the motor is exceptional not only within aviation.

The Antares brushless external rotor electric engine was developed by HTL Biel in Switzerland and it develops 42 kW (56 hp) at 1500 rpm. The motor diameter is only 20 cm (8 in) and weight 28.5 kg (63 lb). The motor outer surface revolves and the shaft is stationary. Propeller blades are bolted directly on to the motor external rotor. Due to the low motor rpm the propeller is big and efficient (83 percent), far better than normal industrial electric motors. The motor overhaul period is 1000 h. The propeller diameter is 2 metres (79 in). The noise level of the Antares is only 40 dB, so low that you can hardly hear it from a distance of 100 m (yards). The results are convincing: The Antares 20E combines a high climb rate (approx. 4.4 m/s / 866 ft/min during takeoff) with a very high attainable climb altitude (approximately 3000 m / 9850 ft in calm air) and very low noise emission.
