Patent ID: 8441159

Claim:
A self-latching sector motor whose net torque is provided by two identical apparatuses where one can be a spare backup, or each apparatus could be operated sequentially to extend life or paralleled for double torque, comprising: a) a housing; b) a magnet-shaft assembly; c) two pair of electromagnetic poles; and d) a pair of stops; wherein said magnet-shaft assembly is magnetized radially North-South; wherein said magnet-shaft assembly rotates within said housing; wherein said two pair of electromagnetic poles extend fixedly and radially inwardly from said housing, towards said magnet-shaft assembly; wherein said electromagnetic poles of an associated pair of electromagnetic poles are diametrically and magnetically opposed to each other which is common to both pairs to react to said magnet-shaft assembly producing net torque, 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 said magnet-shaft assembly that can be backed-up or doubled; wherein said housing is hollow; wherein said housing is generally cylindrically-shaped; wherein said housing has a central axis; wherein said housing has a peripheral wall; wherein said peripheral wall of said housing has an inner surface; wherein said peripheral wall of said housing has a through slot; wherein said peripheral wall of said housing has an outer surface; and wherein said through slot of said peripheral wall of said housing terminates at a pair of ends.
