Abstract
Handwheel systems of the inventive subject matter can be used in a variety of different contexts, including by camera operators. Handwheel systems disclosed in this application provide haptic feedback, which requires high amounts of torque generated by a motor built into the system. PCB stator motors are implemented for their ability to generate high amounts of torque in a compact form factor. Control systems used to drive motors in these systems update at rates that are typically within range of human hearing, and because of the high torque generation, vibrations can be transferred to different components of the handwheel systems, which can cause some components to audibly vibrate. To mitigate or eliminate these audible vibrations, handwheel systems disclosed in this application incorporate adhesive tapes and bushings that prevent vibrations from passing into components that are prone to audible vibrations.
