High aspect ratio positioning system

摘要

High aspect ratio positioning systems are disclosed herein. A high aspect ratio positioning system can be packaged in a thin package that can eliminate some bulky components typically associated with positioning systems such as pancake motors or other motors, geared resolvers, gear trains, and the like. Thus, the high aspect ratio positioning system can be used in applications where volume is limited, without sacrificing accuracy.

主权项

1. A high aspect ratio positioning system comprising:
a support surface; a motor having a circular configuration and disposed adjacent the support surface, the motor comprising
a motor coil assembly attached to an outer magnetic layer that defines an outer diameter of the motor,a commutation coil assembly and a ring of magnets disposed adjacent an inner magnetic layer that defines an inside diameter of the motor; and two resolvers adjacent the motor, wherein a first of the two resolvers comprises a first coil having a first number of windings, and wherein a second of the two resolvers comprises a second coil having a second number of windings, the second number being one less than the first number.
