Title:
ステッピングモータの駆動制御装置及び画像形成装置
Document Type and Number:
Japanese Patent JP5658475
Kind Code:
B2
Abstract:
A driving control apparatus for a stepping motor is provided by which the productivity is improved while keeping the driving performance of the motor at a required level. To accomplish this, a driving control apparatus of the present invention drives a stepping motor by switching an excitation current supplied to a coil of a predetermined phase between a first excitation current value, a second excitation current value greater than the first excitation current value, and a third excitation current value still greater than the second excitation current value. In a first mode for generating a first driving force by the stepping motor, the first through third excitation current values are sequentially switched, whereas in a second mode for generating a second driving force smaller than the first driving force, the first and second excitation current values are sequentially switched.
