Abstract

PURPOSE:To provide stable open-loop control by fitting a control circuit which can read out an exciting phase change timing signal from a memory in response to a changing signal of a step-motor drive voltage. CONSTITUTION:In a memory 5, an exciting phase change timing signal train DS corresponding to the number of shifted steps and the value of a driving voltage VD of a step-motor (SM)2 is stored. An address control circuit 4 transmits an address signal AS designating a memory location (address) of an exciting phase change timing signal TM corresponding to the signal DS to the memory 5 to read out the signal TM. Then, an exciting phase change signal PS is outputted to an exciting phase control circuit 6. This circuit 6 sends excitation signals PA-PD corresponding to exciting phases for selecting either of exciting phases A-D of SM2 to a driving circuit 7. Exciting phases A-D are excited according to signals PA-PD, respectively.
