Embodiment Construction

[0035] image 3 It is a schematic diagram of the end turns 320 extending along the axial direction 321 from the stator having the active end-shaped stator. The laminated sheet 322 has a radially outer surface 324 and a radially inner surface 326. The end turns 320 are part of the winding line, wherein the winding lines have the same length.

[0036] During assembly, the winding line can be curved in the precise point along their length before inserting into the slot of the lamination 322, and is provided in the fixed device (not shown), thereby providing an end turntable 320. After inserting the windings into the slot of the laminate 322, the height of the end turns 320 has two or two layers, including an outer group 328 including layers 1-4 and an internal group 330 including layers 5-8. In group 328, the outermost end turns 320 in layer 1 have a minimum height, and the innermost turns 320 in the layer 4 has a maximum height. Similarly, in group 330, the outermost end turns 320 i...

Abstract

An electric machine (20) has a stator (26) with windings (30) all having the same length. The stator includes a plurality of slots (32). The plurality of windings are mounted in the slots of a stator core and define a plurality of poles circumferentially distributed about the stator core (28). Each winding defines at least a first wrap and a second wrap, wherein each of the first and second wraps circumscribes the stator core. Each of the first and second wraps includes a wire segment disposed in a slot in each pole. The first wrap of each winding is primarily disposed in one of the layers, and the second wrap of each winding is primarily disposed in a different one of the layers. The first wrap of each winding defines a first linear length (X+Y), and the second wrap of each winding defines a second linear length (X) that differs from the first linear length.

Description

[0001] This application is the name "including a motor including a stator with multi-layered ends". The application date is on February 21, 2018, the international application number is PCT / US2018 / 018878, the national application number is 201880005667.7. Patent application. Application. [0002] Cross-reference [0003] The present application claims "ElectriCmachine with Stator Having Multi-Tiered End Turns" in February 23, 2017 No.62 / 462, 540 of US Temporary Patent Application Series No.62 / 462, 540 Priority, the disclosure is incorporated herein by reference. Technical field [0004] The present invention relates to a motor. Background technique [0005] In modern vehicles, the motor is used in a variety of different purposes. For example, a motor is typically used as a starting device, an alternator, a traction motor, and other uses. In these applications, the motor can act as a motor, a generator, or a selectively operated as an electric motor or generator. [0006] F...
