The purpose is to provide the complete motor
. The motor is not geared. It is an inside out BLDC motor. The rotor contains the windings which is in this case fixed (to the brake clamp mounting) and the stator (or the outside of the motor) is connected to the rim and turning. They can not be delivered separately because they are made for each other (dimensions poles etc)
Since there is no gearing and no brushes or commutator the motor is very quite.
But the purpose of this thread is (at this stage) to get commercial contacts in order to set up a low volume serial production. At this moment we are developing the motor.
PS don't look to much at my avatar, it is rather "symbolic" and the real thing is totally different.
