A method of limiting current in a DC motor acts on a full bridge circuit (137)
through which the stator winding arrangement (102) of that motor is supplied
with current. Upon response of the current limiter, energy supply to the stator
winding arrangement (102) from the DC power network is interrupted. The
stator winding arrangement is then operated substantially in short circuit via
semiconductor switches of the full bridge circuit, and the decaying current flowing
in that context serves substantially to continue driving the motor. When that current
has reached a lower value, energy supply from the DC power network to the motor
is once again activated. The effective value of the current flowing to the motor
is preferably reduced when the current limiter responds. The time period during
which that current flows, in the form of current blocks, is then increased in compensatory fashion.
