The original post was in reference to the current required from a power
supply.
No need for a 10amp 60 volt supply--that's 600W, enough to heat
a small room.
If three motors draw 10A max. at 3V, then one would either need
a 3V 10A supply (not-recommended, low high-speed torque)
OR
a 60V supply (20 times the voltage) at 0.5 A (1/20th the current)
A supply that delivers 60V at 10A is overkill.
(I think 60V at 2A would provide a reasonable power margin.)
