Rotor for e.g. stepper motor, has rotor part rotated around rotation axis, and another rotor part serving for transmission of movement of former part, where rotor parts are connected together in rotationally fixed manner

摘要

The rotor has a rotor part (10) rotated around a rotation axis (1), and another rotor part (20) serving for transmission of movement of the former part. The rotor parts are connected together in a rotationally fixed manner, and are moved in a direction of the rotation axis relative together. A clamping unit i.e. spring (30), is used for pushing apart the rotor parts in a direction of the rotation axis, and is made of metal. An extension (24) is moved radially towards the rotation axis, and is molded at the rotor part (20).
