Motor for linear and rotary movement |
| 摘要 |
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 (102) for linear and rotary movement can comprise a stator (104) having a multi-phase coil arrangement including a number of coils or coil sets and a rotor (106) 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 (108) 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. |

1. A device comprising:
an electric motor for linear and rotary movement comprising 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; and a control unit configured to determine currents based on at least said number of coils or coil sets, an angle of rotation of said rotor and a parameter depending on an axial position of said rotor, and to supply said determined currents to said coils or coil sets the control unit being further configured to determine the currents based on a further parameter independent of the axial position and angle of rotation of said rotor. |
