ROTARY ELECTRIC MACHINE

A rotary electric machine includes a rotor that rotates integrally with a rotary shaft and a stator disposed outside the rotor in a radial direction. In the stator, a coil is wound on a stator core, and a coil end of the coil exposed to an outside from an end portion of the stator core is cooled by a liquid coolant. The rotary electric machine further includes a coil end cover formed of an insulating material and configured to cover at least an outer circumference of an upper region of the coil end. A liquid coolant passage through which a liquid coolant flows toward a coil end is provided inthe coil end cover. 本发明提供一种能够利用冷却液稳定地对卷绕安装在定子的线圈的线圈末端部分进行冷却的旋转电机。本发明的旋转电机具备：转子，其与旋转轴一体地旋转；以及定子，其配置在转子的径向外侧。定子在定子铁心卷绕安装有线圈，线圈的从定子铁心的端部露出到外部的线圈末端被冷却液冷却。旋转电机还具备由绝缘材料形成的线圈末端罩，所述线圈末端罩覆盖线圈末端的至少上部区域的外周。在线圈末端罩设有使冷却液朝向线圈末端流动的冷却液通路。
