Abstract
A magnetic flux control system () for controlling the magnetic flux in an electrical machine () with concentrated windings (A-C) has at least one magnetic balancing power supply (A-C), at least one balancing-current controller (A-C) and electrical connections () configured to permit the connection of the balancing-current controller(s) over a segment () of the concentrated windings. The balancing power supply provides galvanicisolation. The magnetic balancing system has further at least one sensor () configured to measure a parameter associated with a magnetic flux, a force, a position, vibrations, voltages, and/or currents. The balancing-current controller(s) (A-C) is(are) connected to the sensor(s) and is(are) powered by the balancing power supply(supplies). The balancing-current controller is configured to control an output current in dependence of a signal representing the measured parameter of the sensor(s). A winding excitation arrangement, an electrical machine and a method for balancing are also disclosed.
