Claims (3)
- 複数のモータコイルと永久磁石列とを相対移動可能に配置し、相対移動する永久磁石列の磁極を検出する磁極センサの検出信号に基づいて、一定周期毎に発生するPWM信号を、前記磁極センサの切替り毎に前記所定のモータコイルに通電してリニアモータを制御し、該リニアモータにより開閉する自動ドアの制御方法において、
前記磁極センサの切替り毎に、新たに前記PWM信号のPWM値の時間積分を開始し、その時間積分値と停止判定基準値と比較してドアの停止を判定することを特徴とする自動ドアの制御方法。 - 前記PWM値にしきい値を設定し、該しきい値以上のPWM値を時間積分することを特徴とする請求項1に記載の自動ドアの制御方法。
- 前記停止判定基準値を、PWM値100%×1秒の時間積分値としたことを特徴とする請求項1又は請求項2に記載の自動ドアの制御方法。
