Scorpion RS-3420 brushless motors โ Full details
Following a brief introduction some days ago Scorpion Power Systems now have full details on their RS-3420 electric brushless motor available. Being a first for the company that is well known for its aircraft brushless motors, the motor sports some interesting features such as a patented screw-type rotor surface for increase flux density and maximised cooling. Also no plastic inserts are used to achieve maximum copper fill for the stator windings while high grade silicone steel and high purity copper wire allow for a high flux density and a minimal internal resistance. Other features include a CNC-machined 7075 heatsink can, sleeve-protected magnets, and a built-in temperature sensor for on-track monitoring with future Scorpion ESCs. The motors are built to comply with the IFMAR rules and are available as 4.5T to 8.5T modified and 10.5T to 21.5T stock variant.
