Product overview
The Scorpion HKIII-5020-520KV is an electric motor component for integration into a powered drive system. Its electromagnetic assembly combines a 50 mm stator diameter and 20 mm stator thickness with 12 stator arms and 10 magnet poles. The winding uses a 13 Turn Delta arrangement and 19-Strand 0.33 mm wire. Mechanical integration must accommodate a 62.1 mm outside diameter, 53.7 mm body length, 5.98 mm shaft diameter and 98.30 mm overall shaft length. Motor weight is 498 Grams (17.56 oz).
Electrical integration is bounded by a maximum 12s LiPo configuration, 90 Amps maximum continuous current and 4000 Watts maximum continuous power. Peak limits rise to 120A and 5320 Watts, each for 5 seconds. The motor has a 520KV RPM / Volt rating, 0.014 Ohms resistance and 1.26 Amps no-load current at 10V. Motor timing is 5deg and drive frequency is 8kHz. Weight including packaging is 928g; this is distinct from the motor’s own mass.
