Cooling device for cooling rotor of asynchronous electric machine that is utilized for driving vehicle, has coolant lines connected to common coolant pipe arranged in rotor shaft, where coolant is circulated through common coolant pipe

摘要

#CMT# #/CMT# The device has a set of coolant lines (8) arranged in pressure plates (5), which extend from a rotor shaft (1) in a direction of conductor bars (3). The coolant lines are connected to a common coolant pipe (7) that is arranged in the rotor shaft. The coolant lines are connected to coolant pipes (9) that are arranged in metal plates (2) and extending in a direction of the respective opposite pressure plates. Another set of coolant lines (10) are connected to the coolant pipes, where a coolant is circulated through the common coolant pipe into a rotor and discharged through the coolant lines. #CMT#USE : #/CMT# Device for cooling a rotor of an electrical machine i.e. asynchronous electric machine that is utilized for driving a vehicle. #CMT#ADVANTAGE : #/CMT# The device allows sturdy and uniform cooling of the rotor of an asynchronous electric machine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic cross-sectional view of a device for cooling an electrical machine. 1 : Rotor shaft 2 : Metal plates 3 : Conductor bars 5 : Pressure plates 7 : Common coolant pipe 8, 10 : Sets of coolant lines 9 : Coolant pipes.
