Abstract
A high torque low speed motor has a nutating assembly driven by a hydraulic or an electric actuator. The nutator assembly drivingly connects to an output shaft through a gear train. Because of a difference in the number of teeth between a gear on the output shaft and a gear on the nutating assembly, the output shaft is driven at a differential ratio as the nutator assembly is driven.
