STATOR OF ROTARY ELECTRIC MACHINE AND ROTARY ELECTRIC MACHINE

摘要

A side surface at the outside of a plurality of teeth portions of one separated core is faced to a side surface of teeth portions of an adjacent separated core, so as to form a second slot which is straddled between the adjacent separated cores, and a first slot is formed by a plurality of teeth portions of one separated core, and a width size of the first slot is identical to a width size of the second slot, and coil conductor storage space is formed in the first slot via a first insulating component, and coil conductor storage space is formed in the second slot via a second insulating component, and a thickness size of the first insulating component is different from a thickness size of the second insulating component.

主权项

1. A stator of a rotary electric machine, comprising:
a stator core which is configured in an annular shape; and a stator coil in which coil conductors are installed to slots which are formed at an inner circumference portion of the stator core; wherein the stator core is configured in such a way that a plurality of separated cores are linked in a circumferential direction of the stator core; and the separated cores include
core-back portions which include an outer circumference surface composing a part of an outer circumference surface of the stator core,a plurality of teeth portions which are protruded from the core-back portions toward the inside in a diameter direction of the stator core and arranged in the circumferential direction of the stator core via a predetermined gap, anda first slot which is partitioned by the plurality of teeth portions; and when the plurality of separated cores are linked in the circumferential direction of the stator core so as to configure the stator core, a side surface, which is positioned at the outside in the circumferential direction of the teeth portions of the separated cores, is faced to a side surface, which is positioned at the outside in the circumferential direction of the teeth portions of the adjacent separated cores, so as to form a second slot which is straddled between the adjacent separated cores; and a width size of the first slot is identical to a width size of the second slot; and the slots, which are formed at the inner circumference portion of the stator core, are composed of the first slot and the second slot; and the first slot installs the coil conductors via a first insulating component; and the second slot installs the coil conductors via a second insulating component of which thickness size is larger than a thickness size of the first insulating component.
