An axial or radial flux electric motor or generator consisting of a housing, a stator assembly(s), and rotor(s) where the stator assembly and rotor are aligned with each other while allowing an air gap between the stator and rotor, with electromagnetic forces being applied between the two when the rotor rotates within the stator. Stator coils are connected by one or more conductive bus bars integrated into the motor housing where the stator coils are affixed to the bus bars to create individual stator phases. The stator assembly is enclosed within a cooling jacket where cooling channels flow a coolant media directly over the stator coils during operation. The flow of coolant is controlled by a set of permeable dividers that direct coolant over the surface area of the coil evenly.
