LINEAR ACTUATOR AND METHOD FOR CONTROLLING THE SAME |
摘要 |
The present invention provides a linear actuator including a motor; a linear driving unit coupled to the motor and including a magnet; a sensor unit configured to sense a change amount of magnetic flux depending on a position of the magnet and convert the sensed change amount of magnetic flux into measured voltage data; a data unit in which reference voltage data corresponding to the change amount of magnetic flux depending on a position of the magnet is stored; and a judging unit configured to compare the reference voltage data with the measured voltage data at the corresponding position of the magnet. The present invention is advantageous in that, by compensation-controlling a position of the motor, feedback control may be performed in the step motor to secure performance of the product to which the present invention is applied |
