ABSTRACT:
Apparatus for providing selectively from time to time in the same member 11 either rotary motion 12 about an axis 13 or linear movement 14 in an axial direction from one position to another comprises: an electric motor 15 including a stator 16 comprising a housing 17 and a magnet 18 for providing a first magnetic field therein; a rotor 19 comprising an armature 20, for providing a second magnetic field, on a shaft 11; all of the above being coaxial about the axis 13; and a commutator 21 (mechanical or electronic) and associated circuitry 22 for conducting electrical energy to the motor 15 to provide, selectively, rotation 12 of the shaft 11 in a selected direction (clockwise or counterclockwise) and/or axial translation 14 of the shaft 11 in a selected direction (toward or away from the first magnetic field). For rotation, the magnetic fields are substantially perpendicular; for translation, they are substantially parallel.
