<p>A magnetic pole wheel (22) is attached to the rotor shaft of the electric drive motor (12) inside the motor housing (16). A circuit board (18) is arranged in the housing (18). This is associated with an electronic control of the drive (10). The circuit board (18) has conductive tracks, electric components and at least one Hall sensor (24) associated with the pole wheel (22). A shell (26) is arranged on the circuit board (18). The shell (26) at least partially encloses the Hall sensor (24). The shell (26) may be integrally connected to the circuit board (18) and may be open towards the wheel (22). USE/ADVANTAGE - For controlling vehicle appliances, e.g. sun roof, windows, etc. Simple device which protects Hall sensor and can be adjusted with positioning of pcb.</p> |
