A method to control a switched reluctance motor (SRM) with a first phase ( ) and a second phase ( ) comprises: aligning the rotor with the second phase ( ); at a first time point (t ), energizing the first phase ( ) with a phase voltage that is substantially constant; monitoring an increase of the phase current (I ) in the first phase ( ) until the phase current reaches a maximum ( ); monitoring a decrease ( ) of the first current (I ) until at a second time point (t ) the phase current (I ) reaches a minimum ( ) and starts to increase again ( ); de-energizing the first phase ( ) at a third time point (t ) that follows the second time point at (t ) at a predetermined time interval; and repeating energizing, monitoring and de-energizing for the second phase ( ) instead of the first phase ( ).
