Electronically controlled electric motor esp. for vehicle ventilator

摘要

The motor is housed in a closed casing with the integrated electronic control in an axial extension of the armature. The screen (22) has flat metallic panels (26-29) perpendicular to the armature axis and supported on a frame (24) in contact w with the power components (36). The fins (32) on the screen are placed in the air flow from a propeller driven by the motor and radial channels in the screen and extending into the panels direct air between the fins. The circuit board (16) carries the components facing the panel, has a central hole for the commutator and supports the brushes (40).
