Stator of motor having bus-bar wiring structure and method of wiring coil in parallel using the same
A stator of a motor having a bus-bar wiring structure according to the present invention includes: a stator core configured of a core base in which a plurality of teeth is formed; an upper insulator coupled to a top of the stator core to insulate the teeth; a lower insulator coupled to a bottom of the stator core; a coil wound around the teeth when the upper insulator and the lower insulator are coupled; and a lower bus-bar housing coupled to a top of the upper insulator and having a plurality of bus-bar insertion units formed to insert a plurality of bus-bars.
1. A stator of a motor comprising:
a stator core configured of a core base in which a plurality of teeth is formed;
an upper insulator coupled to a top of the stator core to insulate the teeth;
a lower insulator coupled to a bottom of the stator core;
a coil wound around the teeth when the upper insulator and the lower insulator are coupled;
a lower bus-bar housing coupled to a top of the upper insulator and having a plurality of bus-bar insertion units formed to insert a plurality of bus-bars;
a neutral point bus-bar insertion unit formed at an outer periphery of the lower insulator; and
a neutral point bus-bar inserted into the neutral point bus-bar insertion unit.
2. The stator according to claim 1 , wherein a plurality of neutral point coil connection units is formed in the neutral point bus-bar insertion unit, and some of coils positioned at a lower portion of the teeth are wired to the neutral point coil connection units.
3. The stator according to claim 1 , further comprising an upper bus-bar housing coupled to a top of the lower bus-bar housing.
