Abstract
One exemplary embodiment of the present invention is a motor control device configured to control rotation of a motor based on a drive signal input from an input terminal wherein the motor control device extracts two or more pieces of information of first drive information indicating a drive state or a drive stop state of the motor, second drive information indicating a rotation direction of the motor, third drive information indicating whether the motor is in a forced stop state, and fourth drive information indicating a rotational speed of the motor from at least one of a duty ratio, a voltage, and a frequency in the single drive signal, and controls the motor.

A motor control device configured to control rotation of a motor based on a drive signal input from an input terminal,
- wherein the motor control device extracts two or more pieces of information of first drive information indicating a drive state or a drive stop state of the motor, second drive information indicating a rotation direction of the motor, third drive information indicating whether the motor is in a forced stop state, and fourth drive information indicating a rotational speed of the motor from at least one of a duty ratio, a voltage, and a frequency in the single drive signal, and controls the motor.
A motor control method through which drive of a motor is controlled based on a drive signal,
- wherein first drive information indicating a drive state or a drive stop state of the motor, second drive information indicating a rotation direction of the motor, third drive information indicating whether the motor is in a forced stop state, and fourth drive information indicating a rotational speed of the motor are included in the single drive signal,
- two or more pieces of information of the first drive information, the second drive information, the third drive information, and the fourth drive information are included in any one of a duty ratio, a voltage, and a frequency of the drive signal, and
- two or more pieces of information of the first drive information, the second drive information, the third drive information, and the fourth drive information are extracted from the drive signal to control the motor.
