Product overview
The Scorpion SII-2212-1850KV (V2) brushless motor is designed for airplane applications. Its electromagnetic assembly combines a 22.0 mm stator diameter, 12.0 mm stator thickness, 12 stator arms and 14 magnet poles. An 11 Turn Delta winding uses 9-Strand 0.21mm wire and delivers a motor constant of 1850 RPM / Volt. Maximum continuous ratings are 22 Amps and 326 Watts, with a maximum LiPo cell count of 4s. No-load current is 1.31 Amps at 10V, and motor resistance is 0.032 Ohms.
CNC-machined aluminum alloy parts receive a gold electroplated finish. The stator uses 0.2mm laminations to reduce eddy current losses, with an epoxy coating to prevent shorts. Winding wire is rated at 180 degrees C (356 F), while the custom-manufactured magnets withstand temperatures up to 200 degrees C (392 F). The motor weighs 58.0 Grams (2.05 oz), with a 27.9 mm outside diameter and a 30.0 mm body length. Its shaft diameter is 2.98 mm, and overall shaft length is 49.0 mm.
The motor comes with 3.5mm male bullet-style connectors already attached. Supplied hardware comprises one Scorpion 22mm Cross Mount, one Scorpion 3mm Threaded Prop Adapter, three matching female connectors for the speed controller, three pieces of heat shrink and four M3 screws. The adapter thread is M5*0.8. Motor timing is 5deg and drive frequency is 8kHz. Weight including packaging is 196.8g. A 2-Year warranty covers defects in materials or workmanship.
