Title:
ELECTRIC MOTOR STATOR
Document Type and Number:
WIPO Patent Application WO/2016/009523
Kind Code:
A1
Abstract:
According to the invention, in order to solve said problem, a power supply line comprises a plurality of lead-out wires to prevent the temperature at the lead-out wires from increasing, thereby obtaining the stator of an electric motor that can make the electric motor smaller in size.
In the electric motor stator according to the invention, stator coils are configured to three-phase AC windings in such a way that: one ends of the U-phase coils are connected to a U-phase power supply line; one ends of the V-phase coils are connected to a V-phase power supply line; one ends of the W-phase coils are connected to a W-phase power supply line; and the other ends of said coils are connected to a neutral point connecting wire. Said U-phase power supply line, said V-phase power supply line, and said W-phase power supply line each comprise a plurality of lead-out wires, and the same number of said coils are connected to each of said lead-out wires.
