摘要
A method of manufacturing a stator assembly for an electrified rotary system includes attaching a first tooth and a second tooth to an inner support. This includes extending the first tooth and the second tooth radially away from the inner support and includes defining an outer diameter opening between the first tooth and the second tooth. The method also includes attaching a winding about the first tooth including moving a conductive member radially into the outer diameter opening to attach the conductive member to the first tooth. Furthermore, the method includes attaching an outer support to the first tooth and the second tooth including closing off the outer diameter opening with the outer support. Also, the method includes removing the inner support from the first tooth and the second tooth after attaching the outer support.
說明書
The present disclosure generally relates to a stator assembly. More particularly, the present disclosure relates to a manufacturing system and a method of manufacture for a stator assembly of a rotary system, such as an e-charger of a vehicle engine system.
Rotary systems, such as electric motors and generators, typically include a stator assembly and a rotor assembly. The stator assembly can include electrically conductive windings that are wound about a stator stack. The rotary system may be included in various components, such as an electrically-driven compressor or e-charger for a vehicle engine system.
Conventional manufacturing methods for the stator assembly may present certain challenges. For example, forming the windings on the stator stack may be difficult, time consuming, and inefficient. Additionally, it may be necessary to perform some manufacturing steps manually, which negatively affects manufacturability.
