    In a nutshell; The motor type is a ' Universal motor '. The configuration is an energized stator and energized rotor with brushes. As it turns out it can run of A.C and D.C. From what i can understand, when run from A.C. the stator coil is 90' out of phase with the rotor by means of the three inductors. Im probably way off there, who cares a badger. In D.C. the inductors essentially dont exist and the outer coil is energized and the brushed rotor turns like a normal D.C. motor.

    At 24v D.C. the drill whirls around at most tedious speed. Im guessing an amp guzzling 48v is needed, maybe more to get the drill up to speed.

    who pointed me in the right direction.

  • It turns.

    The A.C. to DC conversion works, but the coil on the rotor is not tuned for 24v DC. I cant really get the ferric magnets any closer so that bits done. The rotor turns, but not with much gusto. Next step will be to slap in a new 12 to 24v DC motor.

    The motor is out. We have a brushed A.C. motor. Im thinking that if i replace the outer coil with some old DC motor magnets and keep the brushes and inner coil then ill have me a DC motor. Or a melted lump of copper and smoldering wires. Either way its all good.
