Hi Guys

Can any one suggest what are the various methods of performing bench
test for a 20 Kw(25HP) DC electrical variable speed motor.

1) hope the motor powers from some multiple of 6 or 12 volts.
2) lacking the above, build one MAN of a DC supply.
3) take it to a good motor shop

It would cost you more than it's worth to figure out if the torque, speed,
and stall current are within spec, if you had to build or buy the equipment.
