Second Trial of Compass Magnet Motor with U Coupling

It reaches 516 RPM again!!!

We see that using a double Universal Coupling with a 50 mm long shaft just invites more vibration at certain speeds.

Since the turning only takes place above the Universal Couplings there is really no reason to have two.

We think it worked so well with one because it split the vibrations between the magnets and the armature of the Compass Magnet Motor that otherwise would be combined.

Stay tuned:)
