An arrangement for automatic compensation of a rotor of an electric motor, especially of a fan wheel for a fan fixed to the rotor, has an annular chamber which is fastened to the rotor and is filled partly with a damping fluid. In it, freely movable compensation elements are found. The motor is an outside rotor one. Its pot-shaped rotor on one hand is fixed to the rotor shaft on one side and on the other hand is located above the rotor in a partly inverted position. The pot-shaped rotor has the annular chamber with the damping fluid and the compensation elements in the region of the free side wall. |
