Abstract
A paintball loader having a loader body with an exit tube, and a drive assembly including a drive member that rotates about an axis and has at least one fin affixed thereto for moving a paintball toward the exit tube is provided. The drive member has an inner surface and an outer surface. A motor is provided that rotates a drive shaft. At least one first magnet is connected to the drive shaft and at least one second magnet is connected to the drive member. The at least one first magnet and the at least one second magnet have like poles arranged facing each other in a circumferential direction of the drive member about the axis, such that rotation of the drive shaft causes the first magnet to repel the second magnet, rotating the drive member.
