Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022016110
Kind Code:
A
Abstract:
To solve the problem that accuracy of determining a rotational phase of a rotator of a motor deteriorates due to variations in the magnitude of a current supplied to a winding.SOLUTION: On the basis of a value of a current supplied to a winding, a rotational phase is corrected. As a result, it is possible to prevent decrease in the accuracy of determining the rotational phase of a rotator of a motor due to variations in the magnitude of the current supplied to the winding. That is, control of the motor can be kept from becoming unstable.SELECTED DRAWING: Figure 5
