Abstract
A motor spindle having a first electromagnetic drive system including a stator unit and a rotor unit which can rotate about an axis of rotation and has at least one rotor shaft and a tool receiver for receiving a machining tool. At least one bearing unit provides rotationally mounting of the rotor unit in the stator unit. The tool receiver is arranged in an end region of the rotor unit. The stator unit has a stator housing with an end section arranged in the end region of the rotor unit. The stator unit comprises at least one motor, having a second electromagnetic drive system, with a stator and a rotational rotor, wherein the rotor has at least one rotational housing element of the end section of the stator unit.
