| 摘要 |
The invention relates to an arrangement for operating an electrical machine (2), comprising: - a rotor position transmitter (10; 40) for arrangement on the electrical machine (2), in order to provide a rotor position indication depending on a rotor position angle range which indicates the position in which a rotor (6) of the electrical machine (2) is located, wherein a change which occurs during a movement of the rotor (6) between rotor position angle ranges leads to a change in the rotor position indication; - a controller (30; 42), which is designed to associate in each case one or more of the rotor position indications with a commutation angle range which indicates a specific drive state for the stator coils (5), such that a change in the commutation angle range is initiated by a change in the rotor position indication, and in order to change an association scheme of the associations between the rotor position indications and the respective commutation ranges depending on a predetermined rotation correction indication, which indicates the desired rotation direction. |
