Abstract: A microelectric motor has a housing and a rotatable motor shaft extending axially in the housing. The housing has an axial length. A rotor is fastened to the motor shaft and a stator is positioned in the housing for cooperating with the rotor. A receiving chamber is provided in the housing within its axial length. The transducer is positioned in the receiving chamber.

Abstract: In an office machine with an electric drive motor which is arranged in a machine well and on the one shaft end of which an axial blower wheel is fastened to blow a stream of cooling air from an opening in the well in the vicinity of the one end of the motor, an external blower wheel is provided at the motor end facing away from the machine well opening outside the end bell of the motor and the axial blower wheel and the motor are surrounded by an air duct housing partly defined by the machine well and partly by a separate air baffle, in such a way that the air stream is conducted over the motor to the machine well opening to obtain forced surface ventilation.
