An electronically controlled, brushless DC, electromagnetic induction drive apparatus for use in a paintball marker active loader capable of directly driving the feeder element in the active loader while providing independently user selectable torque transfer capability and rotational speed whether used to continuously or intermittently rotate the loader feeder element. A plurality of selectively polarity reversible electromagnets are disposed in the loader housing and act to move a plurality of magnetic drive elements disposed on the rotating feed cone to rotate the feed cone a predetermined amount for each polarity cycle and cause paintballs to be fed into the paintball marker via a feed tube. A controller linked to the marker firing sequence manages the number and frequency of the sequential polarity changes of the electro-magnets to cause the feed cone to rotate in response to sensed movement of paintballs in the feed tube.
