Product information "Scorpion RS-3420 4.5T Bruhsless Motor"
Scorpion Power Systems RS-3420 series Brushless DC car motor. These motors are designed to meet and comply with all standards set forth by IFMAR for use in 1/10th and 1/12th scale electric powered RC racing cars. Scorpion motors are designed from the ground up to meet the demanding needs of racing enthusiasts, and are built with efficient, high-temperature components that allow them to produce the maximum power and speed that is possible. Years of research and development by top engineers and hands on testing by professional drivers has allowed us to make the RS-3420 series the best motors available on the market today!
Patented Screw-type rotor surface to increase flux density and maximize 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 aluminum alloy
