Abstract

PURPOSE: To reduce noise accurately with a simple circuitry with a voltage non- linear resistance element connected in parallel to the power source and an inductance element inserted into the power supply side thereof so that an inductance connection is made in the polarity negative to each other.
CONSTITUTION: A voltage non-linear resistance element 3 is connected to the power supply line of the micromotor M0 being parallel with the power source. An inductance element F having a plurality of coils 8 and 9 is connected closer to the power source in such a manner that a negative inductance connection is made between the coils 8 and 9 with respect to the power supply current. With such an arrangement, whenever the motor M0 produces noise voltage, that above the varistor voltage is absorbed by the voltage non-linear resistance element 3 while that below the varistor voltage can be reduced by the filter action of the inductance element F and a condenser C3.
