Electric machine with configurable stator/rotor cooling

An electric machine includes a drive assembly and a casing. The drive assembly has a stator and a rotor rotatable about a drive axis relative to the stator. The casing contains the drive assembly and has coolant passages, the coolant passages defining a first inlet opening, a second inlet opening, a stator feed circuit, a rotor feed circuit, and an intersection providing fluid communication between the stator feed circuit and the rotor feed circuit. The coolant passages receive at least one coolant input through one or more of the first inlet opening and the second inlet opening to deliver coolant to the rotor through the rotor feed circuit and to the stator through the stator feed circuit.
