Abstract
In a liquid-cooled electric generator, in particular a three-phase generator for motor vehicles and the like, having a rotor, a stator and a housing which accommodates the latter two and forms the bearing for the rotor shaft, as well as a device for liquid cooling (oil or water cooling) having a cooling jacket for a cooling liquid, the cooling jacket, on the one hand, is bounded by the closed external surface of the generator housing and, on the other hand, by a part, which has an accommodating cavity, of an engine block or gear block or similar unit to which the generator is attached and in which it is inserted.
Claims22
A liquid-cooled electric generator for a motor vehicle comprising a housing including two bearing brackets, each of the bearing brackets having a rotor shaft bearing, a rotor mounted on a rotor shaft in the housing with the rotor shaft engaged in the bearings, a stator in the housing, and liquid cooling means including a cooling jacket for a cooling liquid, the housing being received in a part of the motor vehicle which has an accommodating cavity so that the cooling jacket is formed between a closed external surface of the housing wall of the cooling jacket and the cavity of the part of the motor vehicle which forms an outer wall of the cooling jacket.
A liquid-cooled electric generator for a motor vehicle comprising a housing including two bearing brackets, each of the bearing brackets having a rotor shaft bearing, a rotor mounted on a rotor shaft in the housing with the rotor shaft engaged in the bearings, a stator in the housing, liquid cooling means including a cooling jacket provided for a cooling liquid and bounded by a closed external surface of the housing and by a part of a motor vehicle, the housing bearing attached to the part of the motor vehicle, a cooling trough and a rectifier unit mounted in the cooling trough, the rectifier and the cooling trough being located in an additional accommodating cavity of the part of the motor vehicle on which the housing is attached so that an additional cooling jacket is formed between the additional accommodating cavity and internal walls of the cooling trough.
