  • Electric machine with stator cooling teeth
    Patent number: 7518271
    Abstract: An electrical machine, in particular a rotary current generator for motor vehicles, is proposed which has a housing (13) in which a stator (16) is retained, such that a coolant can flow around the outside of the stator (16) from one of its axial face ends (57) to a circumferential region of the stator (16), defining a flow cross section of the flow course through the stator (16) and the housing (13). The flow course is defined toward the stator by outer stator teeth (62) located on the outer circumference of the stator (16).
