Abstract
A driving control device for an actuator comprises a driving device to drive an actuator having an electric motor () and a driving control device () to control the rotation of the electric motor () by controlling the driving device. The driving control device includes an H bridge circuit constructed by four switching semiconductor elements (Trto Tr), and rotates the electric motor in normal and reverse directions by turning on and turning off the switching semiconductor elements (Trto Tr). The driving control device () conducts to activate and to stop the electric motor () by applying a PWM signal to the switching semiconductor elements (Trand Tr) constructing the lower arm of the H bridge circuit ().
