Stator for an electric motor and spring element for the stator

A stator for an electric motor, comprising:

• a cylindrical stator main body having radially inwardly directed stator teeth and a number of axial slots over a circumference thereof;
• a number of spring elements, each having a spring main body inserted, or to be inserted, radially with a form fit into a respective said axial slot, and each having spring arms extending or bent out of the spring main body and projecting circumferentially radially beyond said stator main body;
• said spring arms of said spring elements having a given spring arm width and said spring elements or said spring main body having a given material thickness;
• said number of said spring arms increasing with an increasing axial length of said stator main body;
• and/or
• a ratio of the given spring arm width to the given material thickness of said spring element or said spring main body lying between 10 and 15.

A spring element group for insertion into an axial slot of a stator, the spring element group comprising:

• first spring elements with two spring arms extending or bent out of a spring main body for a stator having a first axial length;
• second spring elements with three spring arms extending or bent out of a spring main body for a stator having a second axial length;
• third spring elements with four spring arms extending or bent out of a spring main body for a stator having a third axial length;
• fourth spring elements with five spring arms extending or bent out of a spring main body for a stator having a fourth axial length;
• fifth spring elements with six spring arms extending or bent out of a spring main body for a stator having a fourth axial length.
