Abstract
A fault tolerant controller arrangement for electric motor driven apparatus is implemented by a plurality of control channels, each of which includes a motor and associated drive circuitry. The implementation is such that the rating of each of the plurality of channels is reduced and all channels are operated such that the load is shared between all operating channels. The arrangement is such that all channels share the load dynamically and statically and that each channel in a system of n channels supplies .sup.1 n of the required load driving force in the same direction.
