Compressible motor, implantation arrangement, and method for positioning the motor

A motor, comprising:

• a rotor that can be driven about in an axial direction;
• and
• a stator, which has a winding arrangement that can be supplied with a current;
• wherein the rotor and stator are each radially compressible and expandable;
• wherein the winding arrangement comprises a plurality of sub-windings each having a radially external part and a radially inner part;
• and
• wherein, when compressed, each radially inner part is overlaid by the radially external part following thereafter.

A method for positioning a motor, the method comprising:

• inserting a stator and a rotor through a channel to a target position, wherein at least the stator is radially compressed,
• wherein the stator has a winding arrangement that can be supplied with a current and that comprises at a plurality of sub-windings each having a radially external part and a radially inner part;
• and
• radially expanding the stator such that the radially inner part of each sub-winding of the plurality of sub-windings can overlay the radially external part following thereafter of each sub-winding of the plurality of sub-windings.

A pump comprising:

• a motor having a stator and a rotor, wherein the rotor can be driven about an axial direction,
• wherein the stator, which has a winding arrangement that can be supplied with a current, is radially compressible and expandable,
• wherein the winding arrangement comprises at least one sub-winding having a radially external part and a radially inner part, and
• wherein each radially inner part is overlaid by the radially external part following thereafter.
