Product overview
The Scorpion HKIV-4025-850KV provides motor power for helicopter installations as part of the fourth-generation HKIV-4025 series. Its physical architecture combines a 40 mm stator diameter and 25 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. For installation planning, the motor has a 49.50 mm outside diameter, a 54 mm body length, a 5.98 mm shaft diameter and an overall shaft length of 84.6 mm.
Electrical integration must accommodate a maximum LiPo cell count of 8s and continuous limits of 95 Amp and 2812 Watt. The higher figures of 110 Amps and 3256 Watts apply for five seconds; motor timing is 5deg and drive frequency is 8kHz. The supplied package contains one motor, three female connectors, three connector covers, four M3 screws and four M4 screws. Motor weight is listed as 347 Grams (10.58 oz), while weight including packaging is 754g.
