摘要:
A device having an adjusting drive and a transfer element. The adjusting drive includes a stator and a rotor. The transfer element converts rotational motion to translational motion. The stator is axially longer than the rotor which axially slides within the stator. The difference in length approximately corresponds to the extent of desired axial movement of the rotor. Thus the rotor is provided with a constant electromagnetic torque over the length of axial movement of the rotor. The transfer element, located within the rotor, has a nut/screw connection, which converts torque into an axial adjusting force. A gap, between the stator and rotor, has a size relating to the desired electromagnetic properties of the motor and acts as a bearing during axial movement of the rotor, thus reducing the number of parts needed for the device parts, the amount of wear and favorable production costs when compared with conventional solutions.
