ABSTRACT:
An electronically commutated motor for dust exhausters with a stator with excitation windings and with a rotor positioned to rotate in an air gap. The rotor has bundled laminations and permanent magnets around its circumference corresponding to the number of poles of the stator. A fan rotor of a ventilator is also provided on the rotor shaft, with the fan rotor connected downstream from the motor in the intake direction of the cooling air. The rotor shaft is connected with a turbine for generation of an intake air current, wherein the fan rotor is positioned in the upper bearing plate of the turbine. The bearing plate is designed in one piece in immediate vicinity of the turbine rotor and has indentations and cutouts in a radially outward direction, whereby air currents of the fan rotor and the turbine rotor flow each from its respective side, with the exit slots for cooling air from the fan rotor and the outlets for the exhaust from the turbine going out from the bearing plate.
