Product overview
The Scorpion HKIV-4025-1100KV is a BLDC propulsion motor for 500-600 size helicopter models, supplied as a motor and installation hardware package. Its electromagnetic architecture combines a 40 mm diameter, 25 mm thick stator with 12 stator arms and 10 magnet poles. The winding uses a single 1.7 mm strand in a 3+3 turn delta arrangement. The HKIV-40 series also incorporates an electromagnetic field design intended to improve compatibility with various speed controllers.
Mechanical integration must accommodate a 49.50 mm outside diameter, 54 mm body length, 5.98 mm shaft diameter and 89.9 mm overall shaft length. Electrical limits are 6s LiPo, 100 Amp continuous current and 2220 Watt continuous power; the 130 Amps and 2886 Watts peak ratings each apply for five seconds. The package contains one motor, three 4mm AMASS connectors, three heat-shrink pieces, four M3 screws and four M4 screws. A shaft and bearing are optional accessories.
