端部绕组

End windings are the exposed coil extensions at the ends of generator stator slots that connect coils to form complete electrical circuits.

技术定义与适配语境
典型 端部绕组 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

End windings refer to the portions of stator winding coils that extend beyond the laminated iron core slots at both ends of a generator stator. These non-active sections provide necessary electrical connections between individual coils to form complete phase windings while allowing mechanical support and insulation. They are critical for electromagnetic performance, heat dissipation, and structural integrity in rotating electrical machines.

定义
End windings refer to the portions of stator winding coils that extend beyond the laminated iron core slots at both ends of a generator stator. These non-active sections provide necessary electrical connections between individual coils to form complete phase windings while allowing mechanical support and insulation. They are critical for electromagnetic performance, heat dissipation, and structural integrity in rotating electrical machines.
工作原理
End windings complete the electrical circuit by connecting individual stator coils in series or parallel configurations. They carry alternating current during operation, creating electromagnetic fields that interact with rotor fields to generate electricity. Their geometric arrangement minimizes electromagnetic losses, manages mechanical stresses from electromagnetic forces, and facilitates cooling through airflow or liquid cooling systems.

常见问题

Why are end windings particularly vulnerable to failure?

End windings experience high electromagnetic forces, thermal cycling, and vibration without the structural support of the iron core, making them susceptible to insulation degradation, mechanical fatigue, and partial discharge.

How are end windings cooled in large generators?

Large generators use direct hydrogen cooling (for hydrogen-cooled machines) or indirect water cooling through hollow conductors, combined with strategic baffling to direct coolant flow across winding surfaces.
