Re: GECKOS 201

Dave:
Why do you talk about 4 times the amp in the formulation.

Masriss posted:
If you are running 3 of these motors, the maximum current draw from
the supply will be 4.5A (3 times 4.5A / 3 for series wired). Using
80,000 times 4.5A / 48V yields 7,500uF. Go with anything between that
and 15,000uF. At 48VDC, use a 63V
