Product overview
The Scorpion HKIII-5020-450KV is a motor component with a 12-arm stator and 10 magnet poles. Its stator measures 50 mm in diameter and 20 mm thick, while the winding uses a 14-turn delta arrangement with 16-strand 0.33 mm wire. For mechanical integration, the motor has a 62.1 mm outside diameter, a 53.7 mm body length and a 5.98 mm shaft diameter. Overall shaft length is 98.30 mm, and motor weight is 501 grams; weight including packaging is 931g.
Electrical integration centers on a 450KV RPM / Volt motor constant and a maximum LiPo configuration of 12s. No-load current is 1.31 amps at 10V, with motor resistance of 0.017 ohms. The continuous limits are 85 amps and 3770 watts. Peak ratings rise to 120A and 5320 watts, each limited to five seconds, making duration a material constraint when sizing the power system. The specified motor timing is 5deg, and the drive frequency is 8kHz.
