There is provided a motor armature structure including an armature that includes: a winding body; an armature core having a plurality of winding cores; and a structure framework, at least a part of the structure framework includes an insulating member, and the armature core includes a molded magnetic material admixture.

Motor armature structure and motor armature manufacturing method

A split-core type motor makes work for connecting lead wires of split coils simple and efficient and reduces manufacturing costs and time taken to connect wires is realized. The split-core type motor includes a plurality of split coils formed by winding coils on split cores on which insulating members have been mounted; a stator formed by disposing the plurality of split coils in an annular shape; crimp terminals that connect lead wires of the split coils by being crimped so that the lead wires of the split coils correspond to a u phase, a v phase, and a w phase of a three-phase AC power source, and form terminals corresponding to the u phase, the v phase, and the w phase, respectively; and a resin mold part that covers the coils and the lead wires while power line connecting portions of the crimp terminals are exposed to the outside.

Split-core type motor and method of manufacturing armature of split-core type motor

The present invention provides a multi-winding motor. Two three-phase exciting windings Sa, Sb are wound on each of the magnetic pole sections of divided cores. Two kinds of discrete winding wirings A, B are wound together with the same winding number onto each of the magnetic pole sectionsA-L of the divided cores. Divided coreswound with the discrete winding wirings A, B are annularly disposed, and are connected in parallel with each other so that the discrete winding wirings are arranged in the order of A, B, A, B . . . within the same connection, and the exciting windings are star-connected to construct two three-phase exciting windings Sa, Sb.
