Embodiment Construction

[0056] Next, the split core type motor and the method of manufacturing the split core type motor armature according to the present embodiment will be described with reference to the drawings.

[0057] The split core type motor of this embodiment uses crimping terminals having a power line connection portion, and the lead wires of the windings wound around a plurality of split cores are crimped corresponding to the u-phase, v-phase, and w-phase of the three-phase AC power supply. Connect the wiring. The crimp terminals form respective terminals of the u-phase, v-phase, and w-phase.

[0058] In addition, in the split core type motor according to the present embodiment, the stator is formed by covering the filling winding and the lead-out wiring with the resin molded part in a state where the power line connecting part of the crimping terminal is exposed. The power line connection portion can be easily provided on the resin molded portion.

[0059] Therefore, according to the p...

Abstract

The present invention relates to a split-core type motor and a method of manufacturing an armature of the split-core type motor. The split-core type motor, which makes work for connecting lead wires of split coils simple and efficient and can reduce manufacturing costs by reducing time taken to connect wires, is realized. The split-core type motor includes: at least a plurality of split coils (50) that are formed by winding coils (5) on split cores (40) on which insulating members (45) have been mounted; a stator (3) that is formed by disposing the plurality of split coils (50) in an annular shape; crimp terminals (80) that connect lead wires (51) of the split coils (50) 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 (30) that covers the coils (5) and the lead wires (51) while power line connecting portions (83)of the crimp terminals (80) are exposed to the outside.

Description

technical field [0001] The present invention relates to a method of manufacturing a split-core motor (split core motor) and an armature of a split-core motor in which a plurality of split cores around which windings are wound are assembled into an annular shape. Forms the stator (armature). Background technique [0002] In general, a split-winding type motor includes: an excitation section provided with a plurality of permanent magnets on a rotor core in the circumferential direction; pivot. [0003] In split-winding motors, current flows through the armature windings to intersect with the magnetic flux generated by the permanent magnets in the excitation section, and a circumferential driving force is applied to the rotor by electromagnetic induction to rotate the rotor. [0004] As a technique related to the armature of a split-winding motor, there is disclosed a split winding in which a first winding and a second winding are respectively wound around and inside the radi...
