110vac to 110dc

The power source does not "dump" amps into the motor. Amps are dependent on what the motor draws. A 15a circuit just means that its capped to 15a by the size of the wiring and limited by the size of the circuit breaker for safety. A 1A motor on a 15A circuit will draw 1A.
Are you sure the motor is AC/DC? Multi voltage motors will have different windings and you have to hook them up according to the voltage you are using. There is usually a data plate on the motor with wiring specifics.
