Rotor for fast running electrical machine of higher dynamics, has base body, which is formed as hollow shaft made of fiber reinforced plastic is arranged between bearing seats

摘要

The rotor (1) has a base body (4), which is formed as hollow shaft a made of fiber reinforced plastic is arranged between bearing seats (2,3). A laminated core (5) and magnet (6) and a bandage (7) are provided on the base body in radial direction. The base body has a form-fit contour corresponding to the laminated core in the area of the arrangement of the laminated core. A cooling channels are provided between base body and laminated core. Radial cooling holes are arranged in the base body, which connects the hollow space of the base body with the cooling channels.
