Wet rotor electric motor and manufacturing method thereof

摘要

The wet-running electric motor has a rotor (6), a stator (4) with pole shoes and a plastic sleeve between the stator and the rotor. Filler pieces (1) are arranged between the pole shoes so that they are connected together to form a closed bore that acts as a support for the plastic sleeve (3) between the stator and the rotor. The filler pieces are made of sheets of electrically insulating material. AN Independent claim is also included for a method of manufacturing an electric motor.
