The sat team is looking recommendations for a brushless motor controller for their momentum wheel. Does the community have any recommendations for a controller?
How about the "Fluid Momentum Wheel" created by AMSAT for one of the P3 birds? (A circular tube of viscous fluid containing magnetic particles that was forced to flow through the tube by pulsing currents through coils wound around the tube. -- Completely solid state. No moving parts.)

I'm curious about this gadget. A Google search of "Fluid momentum wheel" doesn't turn up anything like what is described.
Do you have a link for more info?
Thank you!
