Claim 7:
8. The control unit (8) as claimed in claim 6,
wherein the control unit (8) for determining (400) the contact position (K) on the basis of the motor current (i) is configured
to detect (402) a change in the motor current (i), in particular a first increase in the motor current (ithr),
to determine (404) a corresponding rotor position (φthr) at which the current increase of the motor current (ithr) occurs for the first time,
to determine (406) a contact position (K) from the rotor position (φthr), in particular on the basis of second correlation parameters (K2).
