Problems solved by technology

[0008] However, according to this conventional stator winding method using flat copper wires, there is a problem that the sizes of the stator and the rotor in the motor should be increased in order to improve the output of the motor
[0009] Meanwhile, according to such a conventional stator winding method using a flat copper wire, it is not easy to control the number of turns, thus causing a limitation on high-speed operation (for example, above 7000rpm (revolutions per minute))

Abstract

The present invention pertains to a stator of an electric machine, an electric motor provided with same, and an electric vehicle provided with the electric motor. The stator of an electric machine according to the present invention comprises a stator core having a plurality of slots and a stator winding wound on the slots. The stator winding has a plurality of winding portions which are connected to each other in parallel for each phase, wherein each of the winding portions has segment conductors which are inserted into three or more slots per pole. Therefore, the stator may increase revolutions per minute and have a reduced exterior size while maintaining the same output.

Description

technical field [0001] The present invention relates to a stator of an electric device, a motor having the stator of the electric device, and an electric vehicle having the motor, and more particularly, to a stator of an electric device capable of increasing the number of revolutions and reducing its size, having the electric motor The motor of the stator of the device and the electric vehicle with the motor. Background technique [0002] As is well known, generators such as alternators and / or generators and electromotors such as electric motors and / or linear motors (hereinafter, referred to as "power devices" ) may be configured with a stator and a mover (mover) configured to move relative to the stator. [0003] The stator of the electric device may be configured with: a stator core having a plurality of slots; and a stator winding wound around the slots. [0004] Stator windings can typically be configured by winding relatively thin diameter wire (stranded wire) multipl...
