PURPOSE:To improve the decrease in the generated torque at a high speed time and to suppress a vibration and a noise at a low speed operation time by varying a pulse period time and an applied voltage in accordance with the value set by a table in a memory. CONSTITUTION:A memory circuit 2 stores a pulse period table, an applied voltage table, etc. The output timing pulse 102 of a timer circuit 4 is fed to an exciting controller 6, a latch circuit 10 and an interrupt controller 5. The controller 6 generates a phase signal of 1-2 phase excitation signal in accordance with a timing pulse 102, and applies it to a driver 7 to switch the windings of a pulse motor 8. A latch circuit 10 latches the data stored in a latch circuit 9 synchronously with the output timing pulse of the timer 4, applies output voltage data to a voltage controller 11 and applies a voltage according to the data to the motor 8. |
