Abstract
The invention relates to a motor with a stator (2, 2′) and a rotor (1, 1′), which can be driven about an axial direction (4). The invention is characterized in that at least one of the stator and the rotor, in particular the stator, which has a winding arrangement that can be supplied with a current, can be radially compressed and expanded.
Claims21
A motor, comprising:
- a rotor that can be driven about an axial direction;
- and
- a stator, which has a winding arrangement that can be supplied with a current;
- wherein the stator is radially compressible and expandable, and wherein the winding arrangement has at least one sub-winding, which is reversibly deformable.
1 more element
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,
- radially expanding at least the stator thereafter, and
- after inserting the stator and the rotor through a channel into the target position, displacing the stator and rotor relative to one another in the axial direction.
A pump, in particular blood 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, the motor having a connection element, which extends away from the motor and by means of which the rotor and the stator are displaceable relative to one another in the axial direction.
