APPARATUS FOR DETECTING SPEED OF MOTOR |
| 摘要 |
An apparatus for detecting speed of a motor is disclosed, the apparatus including an amplifier configured to amplify a two-phase sine-wave signal inputted from an encoder based on rotation of a motor; a first conversion unit configured to convert the two-phase sine-wave signal to a digital data; a second conversion unit configured to convert the two-phase sine-wave signal to a square-wave signal; a counter unit configured to accumulate by counting the square-wave signal; and a speed determination unit configured to determine a speed of the motor, by receiving the digital data from the first conversion unit and the accumulated count from the counter unit. |
