Product overview
The Scorpion HKIV-4020-1320KV is a helicopter propulsion motor supplied as a component with connectors and mounting screws. Its fourth-generation HKIV-4020 architecture uses a 40 mm stator diameter, 20 mm stator thickness, 12 stator arms and 10 magnet poles. The winding is a 3+4-turn delta arrangement using single-strand 1.7 mm wire. For mechanical integration, the motor weighs 310 grams and has a 49.50 mm outside diameter, a 49.2 mm body length, a 4.98 mm shaft diameter and an 80 mm overall shaft length.
Electrical integration is defined by a 1320KV RPM/Volt rating, a maximum 6s LiPo battery configuration, 5deg motor timing and an 8kHz drive frequency. Maximum continuous ratings are 90 Amps and 1998 Watts; the higher 105 Amps and 2331 Watts ratings are limited to five seconds. No-load current at 10 V is 5.74 Amps, with motor resistance of 0.006 Ohms. The supplied package contains one motor, three female connectors, three connector covers and four M3 screws, with a packaged weight of 679g.
