  • Wire-winding machine and a wire-winding method for making windings of a rotary electromechanical device
    Patent number: 6659385
    Abstract: A wire-winding machine for forming coils (20) on individual magnetic pole teeth (11a) of a core member (13) which is produced by joining a plurality of core segments (11), each of the core segments (11) having a yoke portion (11c) and a magnetic pole tooth (11a) projectingly formed on an inside surface (11d) of the yoke portion (11c), comprises a core member positioner including a rotating roller (14), large-diameter guide rollers (21) and small-diameter guide rollers (22) which together serve to bend the core member (13) and hold it in a position where the core segments (11.3, 11.5) adjacent to the core segment (11.4) on which the coil (20) is currently wound do not project in the direction of its magnetic pole tooth (11a) beyond a boundary surface (S) of the yoke portion (11c) of the core segment (11.4) on which the coil (20) is currently wound.
