  • Patent number: 4473766
    Abstract: A stator comprises a one-piece U-shaped stator sheet having a pair of elongate parallel legs. The legs form pole shoe bridges at their front ends for their reception of a driven motor. At least one of the pole shoe bridges interconnects the legs adjacent their front ends. A coil-carrying bobbin is mounted on one of the legs, the length of the wound coil being longer than its diameter. A separate yoke sheet is fastened to the legs adjacent rear ends thereof to secure the bobbin on the leg. The stator is formed by first stamping-out a stamping which includes the parallel legs and the yoke, with the yoke being integrally attached to the legs by means of webs. After the stamping undergoes the usual pretreatment, the yoke sheet is separated from the legs, whereupon the coil bobbin is slipped onto the leg from the rear. Then, the yoke sheet is secured to the rear ends of the legs to prevent removal of the coil bobbin.
