ROTARY ACTUATOR ASSEMBLY

摘要

A rotary actuator assembly comprises a knob and an electric motor for providing a haptic effect at the knob and/or for driving the knob. The electric motor comprises a shaft, a gear assembly rotationally coupling the knob to the shaft of the electric motor, the gear assembly including a rotary oil damper damping the rotation of the knob. The rotary actuator assembly further comprises an optical rotation detection device for detecting direction, speed and/or angle of rotation of the knob and/or of the electric motor, wherein the optical rotation detection device is detecting the rotation of an element on the shaft.
