A stator interacts with the rotor (28). The stator has a stator winding strand (26) in an H bridge (22), and a control apparatus (36) which, during operation, performs the steps of: (A) controlling the H bridge (22) so that current pulses (+i1, ?i1) flow through the stator winding strand (26), in alternate directions, each pulse starting at a first point in time (t1); (B) at the beginning of each commutation, starting from a second point in time (t2), operating in short circuit the winding strand (26), in order to cause a decreasing loop current (I*) through the stator winding strand (26), which loop current (I*) reaches zero at a third point in time (t3); and (C) stepwise modifying, toward a minimum, the time interval (TCC) between the first and third points in time (t1, t3).

Abstract: An improved method of commutating an electronically commutated DC motor shuts off application of power between the end of one current pulse and the beginning of the subsequent current pulse. Based upon the instantaneous rotation speed, one calculates at what instant to shut off the power. During the power interruption, the disconnected winding is operated in short-circuit mode using two MOSFET transistors, and the decay of the current is monitored. When the current reaches a predetermined reduced value, the terminals of the winding are switched to a high-resistance state, until the subsequent current pulse is started. This has the advantage that less reactive power occurs during operation, and one need not install as bulky a storage capacitor as the capacitors used heretofore.

Abstract: 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.
