Abstract (en)
[origin: DE19933156A1] The invention relates to an electric drive system comprising a d.c. motor (2) with a control circuit provided with an electronic commutator (3). The invention is characterized in that it provides for a derivation of the adjustment signal (V_i_ref) originating from the induced motor voltage (E_sample) detected by a measuring device and from a reference value (V_i_av) which is used to regulate the speed of the d.c. motor. The invention is further characterized in that the derived adjustment signal (V_i_ref) is used to produce a substantially constant torque for said d.c.motor (2) by adjusting the motor currents (ia, ib,ic).
