Abstract

PURPOSE:To prevent the consumption of wasteful power by setting the base bias voltage of a transistor connected with a DC power source so that the transistor operates in a linear range. CONSTITUTION:When a signal of a low level is applied to an input terminal 11 and of a high level is applied to an input terminal 12, a transistor Q3 and hence Q1, Q5 are turned ON, and a current flows from the left end to the right end of an exciting coil L1. At this time, the left end of the coil L1 drops at the potential in the voltage corresponding to the forward voltage drop of two P-N junctions between and diode D1 and the base and the emitter of the transistor Q1. Accordingly, the left end of the coil L1 is maintained constantly irrespective of the variation in the output voltage of a dry battery B1, and the constant current flows. When a signal of high level is applied to the input terminal 11 and of low level is applied to the input terminal 12, transistors Q6 and hence Q2, Q4 are closed.

Description

[Detailed description of the invention]

"Technical field" Present invention 11. It'i style power supply connected two 1-
A first series circuit consisting of a transistor, a second series circuit consisting of two IC transistors connected to the series circuit in a llCl column, and a connection Jj, between the two transistors of each series circuit. 9 is connected to the motor excitation circuit. ``Prior Art'' Conventionally, in this type of motor excitation circuit, when the output voltage of the DC voltage fluctuates, the voltage applied to the motor excitation circuit also fluctuates in accordance with this fluctuation. For this reason, if a voltage higher than the voltage J required to drive the motor while maintaining the minimum required performance such as the desired speed is applied to the excitation coil, a current higher than necessary will flow through the excitation coil. The flowing power was wasting electricity. Especially u°
When a battery is used as the first current power source, the output voltage of the battery is high while the battery is newly depleted and unused, and more voltage than necessary is applied to the excitation coil, resulting in excessive power consumption and rapid battery consumption. . [Objective 1] The first objective of the present invention is to eliminate the above-mentioned conventional additions and to increase the voltage necessary for the power supply type 10 to have the minimum number of cores < r-t-y. ri convex<Cb, Wi force 11 ((waste 1 J Which C cut motor excitation circuit to suppress consumption I!
