A self-latching sector motor for producing a net torque from two integral independent sources where one can serve as a spare backup or paralleled for double net torque or used alternately for extended life operation. The self-latching sector motor includes a housing, a magnet-shaft assembly, and two pair of electromagnetic poles. The magnet-shaft assembly rotates within the housing. The two pair of electromagnetic poles extend fixedly and radially inwardly from the housing, towards the magnet-shaft assembly. The electromagnetic poles of an associated pair of electromagnetic poles are diametrically and magnetically opposed to each other, and each pair of electromagnetic poles are similarly poled to each other for North and South poles so as to provide the net torque to the magnet-shaft assembly that can be backed-up or doubled. The self-latching torque at the stops is achieved by restraining the magnet-shaft assembly from seeking a position of maximum flux.
