Abstract
In a stator of an alternator for a vehicle, a stator winding has a plurality of conductor segments having ends extending in opposite directions and a plurality of ball-shaped connected portion between the conductor segments forming continuously connected coils. Each of the ball-shaped connected portions is composed of one end of one conductor segment and the other end of another conductor segment.
Claims20
A stator of an alternator for a vehicle including a stator core having a plurality of slots and stator windings disposed in said plurality of slots, wherein
- said stator winding comprises a plurality of conductor segments having a plurality of ball-shaped connected portions between said conductor segments thereby forming continuously connected coils, and
- each of said ball-shaped connected portions comprises an end of one of said conductor segments and an end of another of said conductor segments.
An alternator for a vehicle including a stator core and a rotor, said stator having a plurality of slots and a polyphase winding disposed in said plurality of slots, wherein
- each of said phase windings comprises a plurality of continuous conductors having both ends on a coil-end of said phase winding and a plurality of drop-shaped connected portions located on said coil-end of said phase-winding, each said drop-shaped connected portion connecting two of said conductors at said ends and having a smooth surface.
An alternator for a vehicle including a stator core and a rotor, said stator having a plurality of slots and a polyphase stator winding disposed in said plurality of slots, wherein each of said phase winding comprises a plurality of continuous conductors having both ends on a coil-end of said phase winding and a plurality of connected portions located on said coil-end of said phase winding connecting two of said conductors in series at said ends, said connected portion being a drop-shape which remains after melting at an end surface of said ends.
