A control method and a switching circuit for braking an electronically commutated electrical motor, wherein operation is in a phase period (T) of an inverter relative to at lest one winding, sequentially, both in a motoring mode and a generating operating mode using various cycles (t1-t2, t3-t4) beginning with zero, such that the driving and braking torques associated with the cycles (t1-t2, t3-t4) produce a resultant braking moment averaged over the phase period (T).
