Example Embodiment

[0071] in figure 1 A drive device (1') for generating a translational movement of a movable tappet (8) by means of an electromagnetic rotating machine is schematically shown in FIG.

[0072] The driving device (1') may include, for example, the following components: a housing flange (1) with a stator tube or stator sleeve (2), a protective cover (3), a rotor (4), and windings (12) The stator (5) or stator plate group (5), the screw (6) together with the nut (7) and the tappet (8) and the joint (9) for the control and power electronic devices, the winding and the sensing system (13) In connection.

[0073] The stator (5) is arranged coaxially with respect to the rotor (4) and includes at least one pair of moving threads (6, 7) coaxially integrated therein, and the pair of moving threads includes a non-rotating coupling with the rotor (4) The connected screw (6) and the nut (7) guided linearly in the stator sleeve (2) in a torsion-resistant manner, the nut is preferably rigidly cou...

Abstract

The invention relates to a drive device (V) for producing a translational motion of a movable tappet (8) by means of an electromagnetic rotating machine, comprising at least one rotor (4) and one stator (5), which is arranged coaxial to the rotor (4), having at least one movement-thread pair integrated coaxially in the stator, said movement-thread pair comprising a lead screw (6), which is coupledto the rotor (4) for conjoint rotation, and a threaded nut (7), which is linearly guided in a stator sleeve (2) in a rotationally fixed manner and is rigidly coupled to the tappet (8), the rotor (4)being guided for rotation around the stator (5), a torque being transferred from the rotor (4) to the lead screw (8) by means of a thin-walled flange (10), a rotational fixation (11) of the threaded nut (7) in the cavity of the stator sleeve (2) being provided as a result of interlocking joining of the two.

Description

technical field [0001] The invention relates to a drive device for converting the rotational movement of a rotor of an electromagnetic rotary machine into a translational movement of a movable tappet. Background technique [0002] Stepper BLDC and DC motors are known from DE 10 2013 005 732 A1 and US 9 548 637 B2, which have a friction-fit connection of the rotor to the main shaft via a conical press fit, wherein the corresponding connecting elements are characterized by their inner cone and outer The cone requires a lot of space in the axial direction and therefore the overall length of the arrangement for a given displacement stroke increases. [0003] Furthermore, the arrangements proposed in DE 10 2013 005 732 A1 and US 9 548 637 B2 are provided with spacer (5) (English spacer (5)), which likewise increases the overall length of the arrangement, not here Contributes to movement stroke or driving force. [0004] A linear servo drive is known from DE 10 2015 219 502 A1, ...
