ABSTRACT:
The invention is made to provide a reliable driving system by solving the problem of the conventional apparatus caused by unstable current in the chopper transistor located at the low end of the field winding and armature winding. The over drive control apparatus of the direct current series motor of the present invention, including the field winding and armature winding and driven by power from the battery, comprises a chopper transistor to which the battery is applied, and an over drive contactor connected between the chopper transistor and the field windings to switch the battery power from the chopper transistor to the field winding.
