ABSTRACT:
A variable-speed, multiple-drive, power tool (10) is driven by first motor (18) having a first longitudinal axis (32) and second motor (20) having a second longitudinal axis (100). Second motor (20) drives ring gear (52) of first planetary gear set (48) while first motor (18) drives pinion (36). First end (40) of pinion (36) serves as sun gear (46) for first planetary gear set (48). First planetary gear set (48) drives intermediate spindle (76). Intermediate spindle (76) in turn drives second planetary gear set (82). Second planetary gear set (82) drives output spindle (22) through gear element (90).
