Problems solved by technology

[0002] When introducing a component into a channel system or into a location that is particularly difficult to access, as in the case of implanting a component in a patient, problems often arise because components of this type must be delivered through the narrowest possible opening or channel into the its target position, but will likely have the most dramatic effect once it reaches the target position, especially through the maximum size

Embodiment Construction

[0055] figure 1 It is a schematic diagram of the longitudinal section of the rotor 1 and the stator 2 of the motor. Further components and details have been omitted for clarity. The stator has a winding configuration as shown, which can consist of one or more sub-windings. The rotor 1 has at least one permanent magnet and a hub connected to the rotating shaft 3 . The poles of the rotor 1 or magnets can be driven by the magnetic field of the stator 2 . The shaft 3 is usually rotatably mounted at one or more points in sliding or rolling bearings. The bearing can be fixedly connected with the stator 2 or the casing (not shown) of the stator or the motor as a whole. like figure 1 As shown, it can be seen that the diameter of the stator surrounding the rotor 1 concentrically and coaxially is D in a radially expanded state.

[0056] figure 2 show figure 1 The elements of the electrical machine, in particular the winding arrangement of the rotor 1 and the stator 2 are shown,...

Abstract

The invention relates to an electrical machine with a stator (2, 2') and a rotor (1, 1') that can be driven axially, characterized in that at least one of the stator and the rotor, in particular the stator, can be driven radially Compression and expansion wherein the stator has a current-carrying winding configuration.

Description

technical field [0001] The invention belongs to the field of mechanical and electrical engineering, and is particularly advantageous for use in the field of micromechanics, and is particularly advantageous for application in medical engineering, among other fields. Background technique [0002] When introducing a component into a channel system or into a location that is particularly difficult to access, as in the case of implanting a component in a patient, problems often arise because components of this type must be delivered through the narrowest possible opening or channel into the Its target position, but once there, especially through the maximum size, will likely have the most dramatic effect. [0003] In medical engineering, for this purpose, a method is used in which the corresponding component is compressed so that it is inserted in a compressed state before being introduced into the patient's body to reach its target position, and then unfolded. This technology h...
