Abstract (en)
[origin: EP0727573A1] In the inlet manifold (10) the throttle flap (12) is pivotable about its axis (14) by an electric motor (16) supplied with current via wires (24) from a controller (18). Heat losses in the motor are increased by a sequence of pulses at such a high repetition rate that it cannot react mechanically. The heating is limited by a signal to the controller from a temp. sensor in the immediate vicinity of the motor, measuring e.g. the resistance of its winding.
