A DC tacho-generator has been widely used in such applications as computer peripherals and machine tools. However, this generator has some problems which are the ripple voltage involved in the output voltage and the abrasion of the brush and the commutator. It is said that the ripple voltage of a general DC tacho-generator is from 1.5 to 5% of the output voltage. This ripple voltage must be reduced to very small value in consideration of the influences on control systems.A compensation network of the ripple voltage on this generator was proposed in the previous paper. In this paper, the network is so improved as to operate effectively without losing the high response even when the rotating speed is changed slightly. The performance of the proposed network is discussed in detail, and the method for the design of the network to satisfy the requirements both of the ripple voltage and of the response time is proposed. The experimental results show that the ripple voltage is eliminated perfectly at the steady state, and that the high response is not lost.
