<p>An electrically driven power system includes a carrier structure rotatably supporting a power output. A plurality of individually electrically powered primary drive units are also mounted in the carrier structure. Each of the power units are in driving engagement with the power output for driving said power output in a rotating manner. The electric motors driving the power units are interchangeable thus eliminating a single point motor failure and their smaller size facilitates ease of replacement and repair.</p> |
