Abstract

PURPOSE:To maintain stable convergence regardless of a change of environmental temperature by arranging a temperature sensor adjacent to a viscous damper of a stepper motor to regulate pulse width corresponding to the detected temperature thereof. CONSTITUTION:Silicon oil generally used for a viscous damper 3 changes its coefficient of viscosity mu 1.9-0.5 (g.scm<2>) when the environmental temperature changed 0-60 deg.C. And accompanied therewith the coefficient of attenuation xsi' of the convergence of the viscous damper 3 changes 0.16-0.32. When a temperature sensor is arranged adjacent to the viscous damper of a stepper motor and a driving circuit is porvided with a pulse width regulating function to become the driving pulse width corresponding to the detected temperature thereof the coefficient of attenuation xsi' can be made to come near to a set value. That is to say that the detected voltage of the temperature sensor is made to the digital signals by the A/D conversion to regulate the driving pulse width by the difference from the reference set temperature.
