Abstract
The present invention relates to an electrical circuit for current regulation in DC motors including a sensitivity control means therefor. The circuit includes a means for sensing a predetermined current level in the load of a DC motor. In combination therewith is a subcircuit for cutting-off the load current when the predetermined current level has been reached. Additionally, there is provided means for restoring the load current when, after load current cutoff, the inductive motor current has fallen to a level sufficient to restart the subcircuit.
