A new filter wheel architecture
Designing a rotating hybrid linear stepper motor for space-based optical systems
This report presents a new filter wheel design for use in space-based optical systems. The design integrates a hybrid linear stepper motor into the wheel's rim to generate rotation, leading to a Rotating Hybrid Linear Stepper Motor (RHLSM). Unpowered this motor generates a holding force that can keep the wheel in position during system vibrations. A model was made and simulations were done to investigate motor behaviour and the effect of design parameters. A breadboard was developed to validate motor performance and investigate manufacturability. Design considerations are summarized. The report demonstrates that the RHLSM driven filter wheel is a mechanically simple, robust and compact design. The design shows great potential for a long life time and component cost reduction, and might find use in applications beside filter wheels as well.
