Abstract
PURPOSE: To provide a plurality of speed versus torque characteristics in a DC motor by providing a plurality of armature windings at the motor and operating an external changeover switch.
CONSTITUTION: A main armature winding 1 and auxiliary armature winding 1' are connected respectively to main commutator 2, auxiliary commutator 2', positive and negative main brushes 3, 4 and positive and negative auxiliary brushes 3', 4'. When an external changeover switch 5 is shifted to H side, only the main armature winding 1 is energized but the auxiliary winding 1' is not energized to cause the motor to be rotated at high speed. When the switch 5 is shifted to L side, the main and auxiliary armature windings 1 and 1' are so connected in series as to add counterelectromotive forces to each other. The motor is rotated at low speed equal to 1/2 of the speed when the switch 5 is shifted to the H side.
