I just got one of those cool little scooter motors that Kollmorgen makes/made for scooters and was debating using it for my mill to drive the spindle. What type of power supply would be appropriate for powering it. It being a 24 volt 400 watt motor it works out to be about 17 amps. But that seems to be a bit high. In fact, it seems really high. Are these just not cut out to be used in this manner with a power supply. By that i mean, do i need a battery pack to use them or would a good power supply be enough?
