Abstract
Provided is a method and arrangement for controlling a multi winding set permanent magnet electrical machine in case of a fault in a first group of the winding sets leaving a second group of the winding sets functional, the method comprising: determining a value of a torque generated by all winding sets; and controlling values of currents of the second group of winding sets based on the value of a torque, in order to reduce a damaging torque and/or a torque oscillation occurring and/or to break the machine.
