Abstract

본 발명은 스핀들모터의 속도제어방법에 관한 것으로, 본 발명에 의한 스핀들모터의 회전속도제어방법은 회전방향이 정방향인지 역방향인지를 판단하여 정방향인 경우에는 “브레이크” 명령을 사용하고, 역방향인 경우에는 “킥” 명령을 사용함으로써, 스핀들모터의 제어시간을 단축시킬 뿐만 아니라, 역방향으로 회전하고 있는 경우에도 스핀들모터가 기준 범위내의 속도를 가지고 정방향으로 회전하도록 제어할 수 있는 스핀들모터 제어 방법 을 제공한다.The present invention relates to a speed control method of the spindle motor, the rotation speed control method of the spindle motor according to the present invention determines whether the rotation direction is in the forward direction or the reverse direction, in the case of the forward direction, use the "brake" command, and in the reverse direction By using the “kick” command, the spindle motor control time can be shortened and the spindle motor can be controlled to rotate in the forward direction with the speed within the reference range even when the motor is rotating in the reverse direction. do.

Claims (4)

스핀들모터의 속도제어방법에 있어서, 스핀들모터의 회전방향이 정 방향인지 역방향인지를 판단하는 제1단계; 상기 제1단계에서 스핀들모터의 회전방향이 역방향으로 판단되는 경우, 상기 제1단계에서 스핀들모터의 회전방향이 정방향으로 판단되는 때까지 스핀들모터를 정방향을 가속시키는 제2단계, 제1단계에서 스핀들모터의 회전방향이 정방항으로 판단되는 경우, 스핀들모터의 회준주기를 검출하는 제3단계; 제3단계에서 검출된 회전주기가 PLL자동모드의 제어범위내인가를 판단하는 제4단계 제4단계에서 스핀들모터의 회전주기가 PLL자동모드가 아닌 경우, 제4단계에서 스핀들모터의 회전주기가 PLL자동모드의 제어범위라고 판단되는 때까지 고속회전인 경우 스핀들모터의 속도를 신속하게 감소시키기 위하여 역방향으로 가속하고, 고속회전이 아닌 경우에는 스핀들모터가 계속 가속되도록 대기하면서, 회전주기검출하는 제3단계 및 스핀들모터의 회전주기가 PLL제어범위인가를 판단하는 제4단계를 반복하는 제5단계; 및 제4단계에서 스핀들모터의 회전주기가 PLL자동모드의 제어범위내인 경우 PLL자동모드로 절판하는 제6단계를 포항하는 스핀들모터의 속도제어방법.A speed control method of a spindle motor, comprising: a first step of determining whether a rotation direction of a spindle motor is forward or reverse; In the first step, if the rotational direction of the spindle motor is determined to be reverse, in the first step, the spindle motor is accelerated in the forward direction until the rotational direction of the spindle motor is determined to be the forward direction. A third step of detecting a revolving period of the spindle motor when the rotation direction of the motor is determined to be a square term; 4th step of determining whether the rotation period detected in the third step is within the control range of the PLL automatic mode. In the fourth step, if the rotation period of the spindle motor is not in the PLL automatic mode, the rotation period of the spindle motor is In the case of high speed rotation, the motor accelerates in the reverse direction in order to quickly reduce the speed of the spindle motor until it is determined to be the control range of the PLL automatic mode. A fifth step of repeating the third step and the fourth step of determining whether the rotation period of the spindle motor is in the PLL control range; And a sixth step of outputting the PLL auto mode when the rotation period of the spindle motor is within the control range of the PLL auto mode in the fourth step. 제1항에 있어서, 상기 제1단계에서의 스핀들모터의 회전방향 판단은 모터구동부로부터의 출력되는 U, V, W신호의 순서에 의하여 판단되는 것임을 특징으로 하는 스핀들모터의 속도제어방법.The speed control method of the spindle motor of claim 1, wherein the rotation direction of the spindle motor is determined based on a sequence of U, V, and W signals output from the motor driving unit. 제2항에 있어서, 상기 제1단계에서의 스핀들모터의 회전방향 판단은 모터구동부로부터 출력되는 신호가 U, V, W순서이면 정방향으로 판단하고, U, W, V순서이면 역방향으로 판단하는 것에 의한 것임을 특징으로 하는 스핀들모터의 속도제어방법.The method of claim 2, wherein the rotation direction of the spindle motor is determined in the first direction when the signals output from the motor driving unit are in the U, V, and W order, and in the reverse direction when the U, W, and V order are determined. Speed control method of the spindle motor, characterized in that by. 제1항에 있어서 상기 제3단계의 스핀들모터의 회전주기 검출은 모터구동부로부터의 출력되는 U-신호, V-신호, W-신호 중 한 신호의 1주기를 인지하고, 1주기동안에 경과된 시간을 샘플링 타이머에 의하여 측정하는 방법에 의하는 것임을 특징으로 하는 스핀들모터의 속도제어방법.The rotation period of the spindle motor of the third step is to detect one period of one of the U-signal, V-signal, and W-signal output from the motor driver, and the elapsed time during one cycle. Speed control method of the spindle motor, characterized in that by the method of measuring by the sampling timer. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
