Scorpion RR-3420 ROAR-spec 10.5T brushless motor
Scorpion have introduced their all-new RR-3420 brushless motor. Designed to meet ROAR specifications the motor features an 7075 aluminium case with heatsink design and several cooling openings that also allow to check the stator specifications. Furthermore the motor utilises high-temperature magnets and high-purity copper wires for minimal internal resistance. The stator material is high-grade silicon steel and a built-in cooling fan reduces the internal temperatures while a patented screw-type rotor surface increases flux density and maximises cooling. The motor is currently available as 10.5T variant and should get ROAR approval soon.
