Abstract

A compact in-line dual motor arrangement provides a redundant drive system wherein the respective motors are coupled to planetary gear reducers, each preferably of the dual harmonic drive type. The construction is such that in one stage a first drive motor and one of its two circular splines are connected to a stationary housing, and the second output circular spline is integral with a first circular spline of the second stage. The second circular spline of the second stage transmission together with the second drive motor are connected to an output member.
