Product overview
The Scorpion HKII-7050-330KV is a brushless motor intended primarily for RC hobby applications, with large UAVs, e-bikes and e-boats among its stated uses. Its construction combines gold-anodized, CNC-machined aluminum alloy parts with an epoxy-coated stator using 0.2 mm laminations. The electromagnetic assembly has 12 stator arms, 10 magnet poles and a three-turn delta winding. Winding wire carries a 180 degrees C (356 F) rating. For mechanical integration, the motor weighs 1915 Grams (67.57 oz), with an 82.4 mm outside diameter, 92.2 mm body length and 9.98 mm shaft diameter.
Electrical integration must accommodate a maximum voltage of 50V, maximum continuous current of 200 Amps and maximum continuous power of 10000 Watts. Peak power is 15000 Watts for five seconds. Commercial applications require power requirements and ESC selection to suit the actual use. Installation also requires sufficient clearance between the pinion and main gear to prevent binding. Bearings need periodic maintenance and replacement, with a small drop of oil on each bearing every 5-6 flights. The two-year materials and workmanship warranty excludes bearings and subsequent motor damage caused by bearing failure.
