MOTOR CONTROLLER, FLUID INJECTION DEVICE, AND MOTOR CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a motor controller capable of accurately measuring the tension applied to a paper and controlling the tension based on the measurement result, and to provide a printer and a motor control method. SOLUTION: The motor controller includes a first motor 33 for giving drive force for rotating a roll body RP so as to feed a roll paper P from the roll body RP; a second motor 53 for giving drive force for driving a conveying drive roller 51a provided in a downstream side than the roll body RP along a feeding direction of the roll paper P and for conveying the roll paper P; a tension measurement means 35 for measuring the tension applied to the roll paper P drawn out from the roll body RP by drive of the first motor 33 and the second motor 53; and a motor control means for controlling drive of at least one of the first motor 33 and the second motor 53 based on the measurement result of the tension in the tension measurement means 35.
