The invention relates to a limited-angle torquer of an assembled core concentrated winding, and belongs to the technical field of drivers. The number of stator cores of a stator is the same as the number of magnetic poles of a rotor. Each stator core is provided with winding slots in which radial concentrated windings are uniformly distributed. After the winding slots are insulated, the radial concentrated windings are wound around respective stator cores. The coils in all the winding slots have the same winding direction. All the stator cores are installed outside the rotor and are spliced into a circle. The outsides of all stator cores are fixed by a housing. The windings on every two adjacent stator cores have opposite winding directions. The windings of all the stator cores are connected by an external wire to form a complete stator winding. The limited-angle torquer is very suitable for reciprocating driving with a limited angle and a large stroke.
