Title:
CONTROL CIRCUIT OF PULSE MOTOR
Document Type and Number:
Japanese Patent JPS60190197
Kind Code:
A
Abstract:
PURPOSE:To reduce the vibration and the noise of a pulse motor by varying the high voltage applying time of the motor along the value set by a table in a memory. CONSTITUTION:A memory circuit 2 for storing a pulse period table and the like, a timer 4 for deciding the exciting period, an interrupt controller 5, and timers 11, 12 for setting times for applying higher voltage of 2-voltage drive are connected with bus signals such as address, data and timing from a microprocessor 1. A switch circuit 13 supplies a high voltage V1 to the output only during the time decided by the timers 11, 12. When the circuit does not apply the high voltage to the output, a low voltage V2 is automatically applied to a pulse motor 8 by a low voltage applying circuit 14.
