Abstract

PURPOSE: To inhibit spike-like voltage generated at the energization/deenergization switching by connecting one end of constant voltage elements to a plurality of commutators each, connected to a plurality of coils while the other ends thereof are connected to the external power source by way of brushes.
CONSTITUTION: A slip ring H is provided on the shaft 3 of the armature 5 tangentially facing a brush K for absorbing spark-like voltage. constant voltage elements D1∼D3 comprising Zener diodes are separately connected between the slip ring H and the commutator pieces B1∼B3 of the commutator 4. One end of coils C3 and C1, the other end of the coil C1 and one end of the coil C2, and the other end of the coils C2 and C3 are respectively connected to the commutator pieces B1∼B3. The other ends of the constant voltage elements D1∼D3 are connected to either positive or negative terminal of the DC power source connected between the brushes G1 and G2 corresponding to the commutator 4 through the slip ring H and the brush K.
