Abstract
An injection molding apparatus (5) comprising an electrically driven actuator (200) having a driven rotatable rotor drivably rotatably interconnected to an output shaft (12) or to an output rotation device (16, 430, 500) that is rotatably driven around an output rotation axis (12a, R3a) and a cam device or surface (600) that is eccentrically disposed or mounted off center a selected distance (ED) from the output rotation axis (12a, R3a) in an arrangement such that when the shaft (12) or rotation device (16, 430, 500) is rotatably driven, the cam member or surface (600) is eccentrically rotatably driven around the output rotation axis (12a, R3a).
