Scorpion RR-3420 ROAR-spec 10.5T brushless motor

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.

– Patented screw-type rotor surface to increase flux density and maximise cooling
– Built-in cooling fan on the rotor to increase airflow and decrease internal temperatures
– No plastic inserts are used to achieve maximum copper fill for the motor windings
– Rotor magnets are protected by a metal sleeve for maximum durability
– Built-in temperature sensors allow for on-track monitoring when used with Scorpion ESC
– 200% more cooling surface than other comparable motors for better heat dissipation
– The largest glued surface for the rotor, shaft and magnets of any motor in its class
– High grade Silicon Steel is used in the stator assembly for maximum flux density
– High purity copper wire is used for minimum internal resistance
– High temperature magnets are used to take the heat of competition
– Motor parts CNC machined from 7075 aerospace grade aluminium alloy
