Actuator and auxilliar drive in a vehicule with DC-motor and limiting of inrush current

摘要

A starting-current-limited commutator motor includes a motor-specific, esp. within the motor, control device (OS;IN;KE;VE) automatically activated by an external terminal of the motor (M) for its supply voltage, for limiting the motor current (Im) at start-up. An integrator control signal (S2) rising between a lower starting-point value and an upper final value is used for starting current limitation, specifically by corresponding modulation (PWM) esp. clocking of a delay unit (VE) for the commutator motor (M).
