look at the total watts of the motors.
The chopper drivers cannot supply more, even if you have such an over

one motor is 9 watts
the other 2 total 29.4 watts for a grand total of 38.4 watts.
if you run at 60 volts, then the required current is 2.04 amps for
ALL 3 motors.
If you want to run 6.7 amps, you will have pleanty reserve.
The answer to the treansformers is based on matching units for
parallel use, match amp loads for series.
