Abstract
An electric motor, in particular a stepper motor, comprises a first rigid component having a recess and a second rigid component having a protrusion. The protrusion is at least partially oversized relative to the recess before assembling the first and second component. For the assembly the protrusion is pressed into the recess with a predetermined pressure for forming a rigid connection between the first component and the second component.
Claims17
An electric motor, in particular a stepper motor, comprising:
- a first rigid component having a first recess and
- a second rigid component having a first protrusion which is at least partially oversized relative to the first recess before assembling the first and second component, so that for the assembly the first protrusion is adapted to be pressed into the first recess with a predetermined pressure for forming a rigid connection between the first and second rigid component.
A method of producing an electric motor, in particular a stepper motor, the method comprising the steps of:
- producing a first rigid component, in particular a first stator, with a first recess;
- producing a second rigid component, in particular a second stator, with a first protrusion being at least partially oversized relative to the first recess;
- and
- pressing the first protrusion into the first recess with a predetermined pressure for forming a rigid connection between the first and second component.
