Product overview
The Scorpion HKIII-5025-440KV is a motor component for integration into a powered aircraft assembly. Its electromagnetic architecture combines a 50 mm (1.56 in) stator diameter and 25 mm (0.79 in) stator thickness with 12 stator arms and 10 magnet poles. The winding uses a 12 Turn Delta arrangement and 19-Strand 0.33 mm wire. For mechanical integration, the motor has a 62.1 mm (2.44 in) outside diameter, a 58.7 mm (2.31 in) body length and a 5.98 mm (0.24 in) shaft diameter.
The motor weighs 566 Grams (19.96 oz), with an overall shaft length of 104.30 mm (4.11 in); weight including packaging is 996g. Its electrical specification combines 440KV RPM / Volt with a maximum 12s LiPo configuration, 5deg motor timing and an 8kHz drive frequency. Continuous limits are 95 Amps and 4200 Watts. Peak limits rise to 120A and 5320 Watts for 5 seconds, making duration a material constraint when sizing the power system. No-load current at 10V is 1.15 Amps, and motor resistance is 0.015 Ohms.
