Product overview
The Scorpion HK-3226-1600KV is a brushless propulsion motor developed for 500 class electric helicopters using 425-450mm blades. Its construction combines CNC-machined aluminum alloy parts with a gold-anodized finish, an epoxy-coated stator and 0.2mm stator laminations. The electromagnetic assembly has nine stator arms, six magnet poles and a 7 Turn Delta winding using 26-Strand 0.23mm wire. The winding wire carries a 180 degrees C (356 F) rating; this is a wire rating rather than a stated operating-temperature range for the complete motor.
Mechanical integration must accommodate a 40.9 mm (1.61 in) outside diameter, 50.5 mm (1.99 in) body length and 75.5 mm (2.97 in) overall shaft length. The shaft diameter is 4.98 mm (0.19 in), and motor weight is 239 Grams (7.77 oz). Electrical specifications give a maximum 6s LiPo configuration, 70 Amps continuous current and 1550 Watts continuous power. Peak limits are 90A and 2000 Watts, each restricted to 2 seconds. Motor timing is 5deg and drive frequency is 8kHz.
The supplied package contains one motor, three female connectors, three heat-shrink pieces and four M3 screws; 4mm male bullet connectors are already attached to the motor. A propeller adapter is excluded, so propeller installation requires a separate adapter for a 5mm shaft. Installation also requires sufficient clearance between the pinion and main gear to prevent binding. Bearings need periodic maintenance and replacement, with a small drop of oil every 5-6 flights. The 2-Year materials-and-workmanship warranty excludes bearings and motor damage resulting from bearing failure.
