Re: AC Adaptor?

Al's reply got me curious...so I connected a lab power supply to an RS540 mabuchi motor (the BaneBots motor) and switched it on and turned up the voltage. With the current limiting set to 2.0 amps, the ammeter indicated a spike to about 1.5 amps, and running currrent of about 1.0 amps with the voltage adjusted to anywhere from a couple volts to 10 or so.

I think my estimate of 10 amps needed to test the system, having the motors without mechanical load on them, is probably reasonable, asuming you don't try to run more than two motors at once.
