Product overview
The Scorpion HKIV-4020-1060KV is a helicopter propulsion motor supplied as a component for integration. Its electromagnetic architecture combines a 40 mm stator diameter and 20 mm stator thickness with 12 stator arms and 10 magnet poles. The winding uses a 4+4-turn delta arrangement with single-strand 1.6 mm wire. Its speed constant is 1060KV RPM/Volt, while electrical characteristics include 0.009 Ohms motor resistance and 4.03 Amps no-load current at 10 V.
Mechanical integration must accommodate a 49.50 mm outside diameter, 49.2 mm body length, 4.98 mm shaft diameter and 80 mm overall shaft length. Motor weight is 310 Grams. The maximum LiPo configuration is 6s, with continuous limits of 78 Amps and 1731 Watts; the 90 Amps and 1998 Watts peak ratings each apply for five seconds. Timing is 5deg and drive frequency is 8kHz. The package contains one motor, three female connectors, three connector covers and four M3 screws, and weighs 682g including packaging.
