LOCK CURRENT SUPPLYING METHOD OF PULSE MOTOR

Title:

LOCK CURRENT SUPPLYING METHOD OF PULSE MOTOR

Document Type and Number:

Japanese Patent JPS6135199

Kind Code:

A

Abstract:

PURPOSE:To suppress the fluctuation of a pulse motor rapidly by supplying an exciting current for locking with a current value larger than the exciting current value during operation. CONSTITUTION:A main controller 12 delivers a switching signal to a switch 19 at a timing when a rotation pulse motor 8 is locked to shift the switch as designated by a broken line to supply a reference voltage E from between resistors R1 and R2. Accordingly, the voltage E becomes a high voltage value to be supplied to an operational amplifier 18. In other words, when the motor is locked, a locking exciting current is increased larger than the exciting current during the operation of the pulse motor to generate a large torque to brake a rotational shaft fluctuated by the inertia to rapidly stop it.
