power source for d.c motor

[shaondip]

hi ! im new to this forum and i have a question
i have salvaged four RS 385 PH motors from a car(specs. http://www.mabuchi-motor.co.jp/en_US/cat_files/rs_385ph.pdf). i need each of them to run providing the maximum torque they possibly can for repeated periods of 30 seconds or so. as far as i know in a permanent magnet d.c motor the torque is dependent upon the supply current only. Here the stall current is in the range of 3 amps .will i get a stall torque that is close to the specified stall torque if i run the motor using a 12v 3 amp AC to DC adapter?
also will there be heating issues? if so how to overcome them?

if they are 12V motors, then use 12V power. if there are any heating issues, try a fan.

Yes.  If your motor is rated at 3A stall current, a 3A power supply will provide the rated stall torque.
I don't know if you will have heating issues.  It depends on the motor.
