Generator controller of vehicle electrical system, controls current passing through rotor winding of electric machine to measure actual value of base quantity from actual value of system variable and output system variable actual value

摘要

The generator controller (1) controls the current passing through the rotor winding (2) of an electric machine (20) which is adapted to measure the actual value of base quantity from the actual value of system variable and to output an actual value of the system variable at the output terminal for a generator control unit (200). The output and/or the input of the controller are designed as Fieldbus interface, such as controller area network (CAN) bus interface or local interconnect network (LIN) bus interface. Independent claims are included for the following: (1) a method of operating an electrical machine; (2) a computer program for operating electrical machine; and (3) a machine-readable storage medium storing program for operating electrical machine.
