  • Patent number: 5488275
    Abstract: A control circuit for limiting the current flow to a direct-current driven motor, to reduce current spikes at motor start up, including a voltage-regulated, current-passing device for passing current from a direct voltage source to the motor, the device having a default configuration such as to permit full current flow there-across when the voltage is initially applied, a voltage drop device interposed the voltage source and the voltage-regulated, current-passing device responsive to the current flow to the motor and a variable-voltage output device responsive to the voltage drop developed in the voltage-drop device for providing a subsequently changing voltage for input to the current-passing device for limiting the current flow therethrough following initial application of the voltage.
