摘要： An electric machine (100) having an electrically insulative manifold (200) is disclosed. In one example aspect, an electric machine (100) includes a non-electrically conductive manifold (200). The manifold (200) defines a chamber (220) operable to receive a cooling fluid. The electric machine (100) includes a prime winding (120) in fluid communication with the chamber (220) and one or more secondary windings (122) in electrical communication with the prime winding (120) and in fluid communication with the chamber (220). Further, the electric machine (100) includes an electric machine terminal (250) extending through the non-electrically conductive manifold (200) and coupled with the prime winding (120). The electric machine terminal (250) can provide or collect cooling fluid from the chamber (220) of the manifold (200) and can act as the electrical connection point for directing electrical power to or from the windings (120) of the electric machine (100). The non-electrically conductive manifold (200) electrically decouples the windings (120) of the electric machine (100) despite each winding receiving cooling fluid provided or collected at the manifold (200).
