More Information
Summary:The electric machine (100) comprises a rotary magnetic assembly (10), preferably comprising permanent magnets; a stationary magnetic assembly (20), preferably comprising electromagnets; a rotary hub (30) having a cylindrical shape and a tube-shaped recess (31) for housing the rotary magnetic assembly (10); a sleeve (40) positioned around the tube-shaped recess (31) so to surround it, and mechanically coupled to the rotary hub (30). The sleeve (40) has a first end region (41) and a second end region (42) which are sealed to the rotary hub (30) so to fluidly isolate the tube-shaped recess (31). The rotary hub (30) comprises at least one inner channel (250, 350, 450) which is fluidly coupled to the tube-shaped recess (31).
