Electrical machine e.g. electric steering motor for motor vehicle, has fan blades which are arranged on rotational angle transmitter wheel in circumferential direction and are associated with fan wheel which surrounds transmitter wheel

摘要

The electrical machine (1) has a rotor shaft (2) and a rotary encoder (11). The rotor shaft is connected to a rotational angle transmitter wheel (9) in a rotationally fixed manner. The rotational angle transmitter wheel is provided with several fan blades (15) in the circumferential direction. The fan blades are associated with a fan wheel (14) which partially surrounds the rotational angle transmitter wheel. The fan wheel is designed as radial fan wheel or axial fan wheel.
