What type of AC to DC power supply should be used to drive a DC motor? I have seen switched and linear power supplies. Some are regulated and others non-regulated. I want to use this instead of the large car size battery the motor currently uses.
The power supply that should be used to drive a DC motor is DC power supply. For instance, if it is used in brushless DC motors, the motor controller converts DC to AC. The DC motors require no commutation. Thanks Engineer Remon
A switcher or a linear power supply will work. Even a non-regulated DC power supply having considerable ripple should be good for powering a DC motor.
A simple and inexpensive DC motor power supply can consist of a battery charger, having a charging current rating higher than the motor, connected to a car size battery. The car battery is to stabilize the voltage at less than 14 volts.
If the battery charger outputs are floating - not internally connected to the AC power ground wire - two 12.6 volt batteries and two chargers can be series connected.
I suspect that the typical car battery charger has floating outputs but you'll have to get one and see. I searched online for schematics or a manual that specifically stated this but didn't find one.
