Abstract
A power machine or excavator includes a swivel assembly coupling the upper frame portion to the lower frame portion, while providing accurate slew position measurement using a swivel sensor which is positioned to reduce measurement errors over a thermal range of operation of the power machine. The swivel assembly includes a swivel barrel configured to be attached to the lower frame portion of the power machine, and a swivel spool configured to be attached to the upper frame portion. The swivel sensor is positioned and configured to provide a sensor output indicative of a rotational position of the upper frame portion relative to the lower frame portion.
