ELECTRIC MACHINE AND METHOD FOR COOLING AN ELECTRIC MACHINE

摘要

An electric machine includes an inner fan in an inner cooling circuit and an outer fan for producing an outer coolant flow that is separate from the inner cooling circuit. The inner and outer fans are connected to a common shaft of the electric machine and have opposite delivery directions along an axial direction of the electric machine. The outer fan is arranged in a fan housing which has an inlet opening for the inward flow of a coolant of the outer coolant flow, and includes an air directing device, which guides the coolant in a line section which extends in the radial direction of the electric machine from the inlet opening towards the outer fan.
