Document Type and Number:
Japanese Patent JP2016073143
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor control device which avoids operation stop due to torque shortage when a motor starts rotating and achieves low current consumption.SOLUTION: A motor control device comprises: a supply current control section which controls current to be supplied to a stepping motor; a rotation detection section which detects whether the stopping motor can rotate or not; and a control section which stores a predetermined lowest supply current value as a set value of supply current in a predetermined rotation frequency which the rotation detection section detects rotation of the stepping motor, when the stepping motor is operated at a predetermined rotation frequency, by a predetermined supply current outputted by the supply current control section.SELECTED DRAWING: Figure 1
