ABSTRACT:
Process for the control and electronic regulation of the supply current in an electric motor fed from a fixed voltage direct current source by means of a chopper controlled by logic signals for turn on (SI) and for turn off (S2), characterized in that a measuring voltage representing the current passing through the motor is produced, and also a command voltage representing the command current required to be imposed on the motor, in that the signals are compared and in that depending on the result of this comparison, the progressive positive or negative charge of a memory condenser (CM) is produced, the charge voltage of which is itself compared (A1) with a reference voltage.
