Electronically commutated DC motor for a fluid pump

摘要

The motor has a disk-shaped pump rotor rotatably mounted on a pump housing (3) and composed of a pump wheel with pump blades and permanent magnets. A separation wall (11) separates a pump chamber from a drying chamber, and is arranged in an axial gap between the rotor and stator poles (14) of the motor. The stator poles are insulated against individual stator windings by an insulating body (15). The insulating body is integrally provided with receivers (21a, 21b), and a conductor plate is fastened to the insulating body in an axially and radially form-fit manner.
