Product Description
Scorpion SII-55 series is the second generation of high efficiency electric motor from Scorpion that are widely used in the size of 30cc to 50cc airplane, with proven technology in new magnet configuration and housing design to provide higher efficiency, higher power, less eddy current losses with lower internal resistance than our previous S-55 series.
Scorpion starts with premium material with high quality aluminum alloy parts that are produced on the latest CNC milling machines. These parts are then gold Electro-coated to provide a beautiful, long-lasting finish. The stators are made by top grade 0.35mm laminations to give maximum efficiency, and minimum Eddy current losses. The stators are epoxy coated to prevent shorts, and are wound with wire that is rated at 180 degrees C (356 F). The magnets used in Scorpion Motors are custom manufactured to be able to withstand high temperatures.
Scorpion Motors are built to last, and are backed with a 2-Year warranty against defects in materials or workmanship.
