CONTROL DEVICE FOR A ROTOR BLADE SERVO DRIVE OF A WIND TURBINE |
摘要 |
A control device comprising an electric motor (19) with a support (20) and a rotor (21) movable relative to the support (20), a control unit (45) by means of which the speed of the rotor (21) can be controlled as a function of an intended speed (nsoll) and a field-weakening unit (46), by means of which a weakening of field can be induced as a function of the speed (n) in an upper speed range, wherein in part-load operation of the electric motor (19) a weakening of field can be induced as a function of the current load of the rotor (21) by means of the field-weakening unit (46) in a basic speed range lying below the upper speed range. |
