  • Actuator
    Patent number: 11114919
    Abstract: An actuator is provided which comprises an actuator housing having an inside surface defining a stator-receiving portion and a stator. The stator-receiving portion comprises a rotor support element, and plurality of guide projections which are spaced-apart about the rotor support element, the plurality of stator-abutment projections being integrally formed with the inside surface. The stator has a plurality of locator recesses which are engagable with the plurality of stator-abutment projections when the stator is received at the stator-receiving portion of the actuator housing to locate the stator relative to the actuator housing.
    Type: Grant

  • Method of producing an electric motor
    Patent number: 7165313
    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.
