Patent Searching and Data


Title:
シート搬送装置及び画像形成装置
Document Type and Number:
Japanese Patent JP6548627
Kind Code:
B2
Abstract:
A sheet conveying apparatus for conveying a sheet includes a conveyance roller, a motor, a phase determiner, and a controller. The phase determiner determines a rotor rotation phase of the motor that drives the conveyance roller to convey the sheet. The controller controls so that a value of a rotor torque current component becomes a target value of the torque current component and controls so that an excitation current component value becomes a target value of the excitation current component, and controls to reduce a deviation between a command phase and the determined rotation phase. The controller controls so that a magnetic flux penetrating through a winding is weaker than a magnetic flux of the rotor, and so that a magnetic flux penetrating through the winding in a second period is stronger than the magnetic flux penetrating through the winding in the first period.
