Title:
STATOR HAVING BUS BAR STRUCTURE, PROPELLER DRIVING MOTOR USING SAME, AND METHOD FOR MANUFACTURING STATOR
Document Type and Number:
WIPO Patent Application WO/2023/018053
Kind Code:
A1
Abstract:
A stator having a bus bar structure that enhances assembly productivity and durability by adopting the bus bar structure comprises: a division type stator core in which a plurality of division cores are assembled in an annular shape; upper and lower insulators surrounding the outer circumference of teeth of the division cores; a stator coil composed of a plurality of core groups continuously wound onto three teeth for each phase; a plurality of bus bar brackets coupled to the insulators so as to bind two division cores; U-phase, W-phase, and V-phase bus bars on which a connection terminal to which a start terminal of each core group is connected is protruded; a common electrode bus bar on which a connection terminal to which an end terminal of each core group is connected is protruded; and a stator support that insulates between coils so as to integrate the plurality of division cores.
