AbstractA non-continuous brush and commutator segment torquer motor having a single radial air gap. The motor can be placed on the opposite side of the gimbal center line of a payload. This arrangement minimizes torquer mass, as well as providing greater clearance for the gimbal payload to travel through larger angular excursions. Hence, all payloads which are gimbal mounted, such as radar antennas, can be located closer to the gimbal center and can be driven through larger look angles.
