Abstract
In summary, the present invention relates to a device, a method and a computer program enabling a rotating and translating movement by means of a single motor. An electric motor () for linear and rotary movement can comprise a stator () having a multi-phase coil arrangement including a number of coils or coil sets and a rotor () being movable along a direction of its rotational axis and having a number of poles respectively comprising at least one permanent magnet. A control unit () may determine currents based on at least the number of coils or coil sets, an angle of rotation of the rotor and a parameter depending on an axial position of the rotor, and supply the determined currents to the coils or coil sets.
