Patent ID: 10630138

Abstract:
A reciprocating ramp motor, including: an output shaft including an axis of rotation; a first electro-magnetic device including a first coil; an annular core plate disposed about the output shaft and axially off-set from the first electro-magnetic device in a first axial direction; a roller device; and a first ramp non-rotatably connected to the output shaft; and sloping in the first axial direction along a first circumferential direction. The first coil is arranged to be electrically energized to displace the annular core plate in a second axial direction, opposite the first axial direction. Displacement of the annular core plate in the second axial direction is arranged to roll the roller device along the first ramp in the second axial direction. Displacement of the roller device along the first ramp in the second axial direction is arranged to rotate the output shaft in the first circumferential direction.
