Description

Mailing list for discussions on designing and building brushless electric motors and controllers. The motors built so far, range from 20W to 2kW. You can also build from kits. LRK and CD-ROM outrunners have different winding diagrams!

Outrunners are inside-out motors, the coils are stationary, housing and magnets rotate. They feature a high torque AND they can rev. There is no need for a gearbox, which means less weight, less $$$'s or €€€'s, no losses, no whining and no wear. The motor can swing a bigger prop, resulting in a higher overall system efficiency. The builder can tailor the motor to the application by adapting the number of winds. (Motor pictures by Detlev Koch)
