ELECTRIC MOTOR ARRANGEMENT FOR A MEDICAL, ESPECIALLY DENTAL, TOOL HOLDER

摘要

The electric motor arrangement has a rotor (R) with a rotor shaft, a stator (2) arranged around the rotor with reference to a rotor shaft and a medium pipe (4) for transmission of a medium. A core element is formed by injection of a high temperature polymer, which closely surrounds both the stator and the medium pipe with reference to rotor shaft.
