Motor KO Demon Seed 2208 1750kV 4-6S for FPV drone

KO tech is the very first motor company to incorporate a cooling system to RC brusless motors that does not rely on fans or fin style designs.

KO Demon Seed motor for FPV race drone with camera

The traditional fan or fin styled design calls for a fan machined in to the bell with on the inside or outside of the bell, this method has 2 major flaws. Firstly this design is "handed" meaning CW rotating motors must have a fan design orientated differently to a CCW voting motor if the fan is to be effective. Second is the fact that a fan or fan shaped spokes design robs the motor of power to drive the fan and In turn lowering response times, ultimate RPM and ultimate available torque.

KOtech has developed ACPC to compress oncoming air directly at the bell spoke face forcing the air past the spokes and directly into the stator and magnet assembly.

This lowers the temps increases torque and dramatically increase response times all the way along the rpm  range. As a bonus the angled ring that forms the ACPC design is used as a counter balance used to reduce the amount of putty used to balance a motor bell.

We are able to "clock" the ACPC ring a full 360° during the ballance procedure effectively halving the amount of putty needed to achieve a reading of "True" on the test equipment . This allows us to further reduce the bells weight and in turn improve motor response times.

Lastly because of this ability to reduce the amount of  balance putty needed we have also been able to reduce the lip at the base of the motor used as a rebate to retain the putty under high RPM centrifugal forces further reducing weight and Improving response times.
