Report of test on cryogenic cooler motors
Abstract
This document provides test data obtained from twelve prototype DC brushless outer rotation motors designed to operate at 20 oz-in and 1100 RPM. Power input, speed-torque, and efficiency curves are provided for ambient temperatures between -54C to 82C and for applied input voltages from 18 to 32 VDC.
