PURPOSE:To smoothly continuously operate a pulse motor by suitably varying the phase of each exciting coil of the motor, thereby supplying a PWM wave. CONSTITUTION:PWM waves of different phases suitably obtained from the output terminals a'-d' of the output port 10 of a high frequency pulse generator 1 which is formed of a microprocessor are respectively inputted to the bases of drive transistors Ta-Td, an are supplied to the exciting coils 4, 5 of a pulse motor 2 through terminals a-d. A high frequency pulse generator 1 has an input port 6 which receives a command signal of the PWM wave output from the exterior and drives an arithmetic unit 7, an ROM8 which sets the program of generating the PWM wave and controlling and programming a player, an RAM9 of reading and writing various data and an output port 10. |
