Title:
MOTOR CONTROL DEVICE, SHEET CONVEYING DEVICE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2018050404
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem in which: when the frequency of a harmonic content included in a detected current value of a driving current is changed, if the degree of a digital filter is increased, the usage of memory is increased, resulting in an increase in cost.SOLUTION: A motor control device performs thinning-out processing on data of a current value and a voltage value, and performs filter processing on the current value and voltage value to which the thinning-out processing is applied through the thinning-out processing. As a result, a signal of a harmonic content can be reduced without increasing the filter degree.SELECTED DRAWING: Figure 9
