A method for adjusting an operational performance of an electric machine, wherein the electric machine comprises a stator and a rotor, wherein the stator comprises a set of N phase windings, wherein each N phase winding, of the set of N phase windings, forms p poles around a circumference of the stator, and wherein each p pole, of the p poles, is formed by at least one winding sector, the method comprising:
- deactivating, by a system comprising a processor, a first sub-set of winding sectors, wherein the first sub-set of winding sectors comprises at least one winding sector;
- and
- triggering, by the system, an AC drive signal for a second sub-set of the winding sectors such that the rotor is rotated using the winding sectors of the second sub-set.
