Compass Motor Longer Upper Axle No Bearings 3D Prints 330 RPM

After trouble with bearings they were removed. The compass magnet motor now does near record speeds again but is still a little off balance.

It has some 3D printed parts so the motor is perpendicular to the armature and also lined up with the axles.

Also an Alwonder size 12 nickel plated ball bearing cloak lock fishing swivel is used to hang the motor armature from.

It can go faster but we are quite pleased with 330 RPM.

It seems the vibration could have a number of causes but making the upper axle longer helps reduce it. No doubt a more precise future model will have much less vibration.

Stay tuned:)
