A DC motor control Circuit for providing improved starting and stopping control is provided. The control circuit includes a DC constant voltage source, a control transistor, a DC motor and a switching transistor having a first switching control electrode and two further electrodes defining a current path connected in parallel with the DC motor. The parallel connection of the DC motor and switching transistor electrodes is further connected in series with the DC constant voltage source and control transistor. A drive circuit is coupled to the switching transistor control electrode and is adapted to produce a starting signal for opening said switching transistor current path, and a stopping signal for closing said switching transistor current path in response to the respective application of either a stop signal or a start signal to the driving circuit.
