In a preferred embodiment, a linear/rotary motor (10), including: first and second stator structures (14, 16), having magnetically coupled thereto, respectively, first and second rotors; a first, externally threaded shaft fixedly attached to the first rotor and extending axially therefrom, such that rotation of the first rotor causes rotation of the first, externally threaded shaft; a second shaft (16), having a splined external surface, extending through a complementarily shaped opening defined through the second rotor, and axially movable with respect thereto, such that rotation of the second rotor causes rotation of the second shaft (16); and the second shaft including threaded apparatus cooperatively engaging the first, externally threaded shaft, such that rotation of the first, threaded shaft can cause linear motion of the second, cylindrical shaft. The motor can be operated to provide rotary, linear, or simultaneous rotary and linear motion of the second shaft (16).
