摘要

The machine has an air inlet, an half-open cover, a suction recess, an air passage, a sediment separating grid, outer loop cooling ribs, a stator cooling channel, exhaust air openings, a ventilator for cooling a stator laminated core and coil ends. A housing is arranged at a rotor to encapsulate the rotor. Inner air channels (31), outer vent holes (32), air gap (33), inner cooling ribs (34) are arranged within the housing, and have a closed cooling circuit with an inner ventilator (29) that is integrated into a clamping ring of the rotor., where bearing plates (6, 7) have a magnetic ring.
