| description | PROBLEM TO BE SOLVED: To provide a control system in which erroneous judgment is prevented from occurring when operation of a fan motor is switched between forward rotation and reverse rotation.SOLUTION: The control system includes a motor, an interface circuit, a motor controller, and a detection control circuit. The interface circuit receives and converts a pulse width modulation signal. The fan dissipates heat when the motor is operated in a forward rotation mode, and eliminates dust when the motor is operated in a reverse rotation mode.. The detection control circuit reads a duty cycle of the converted pulse width modulation signal in real time. When the motor is operated in the forward rotation mode, the detection control circuit drives a motor controller to control a rotation speed of the fan according to the duty cycle. When the duty cycle is smaller than or equal to a first threshold value, the detection control circuit drives the motor controller to switch an operation mode of the motor from the forward rotation mode to the reverse rotation mode.SELECTED DRAWING: None
【課題】ファンモータの動作が正回転と逆回転との間で切り替わる際の誤判断を避ける制御システムを提供する。【解決手段】制御システムは、モーター、インターフェース回路、モーターコントローラ及び検出制御回路を含んでいる。インターフェース回路はパルス幅変調信号を受け取り、変換する。ファンは、モーターが正回転モードで動作しているとき、熱を放散し、モーターが逆回転モードで動作しているとき、ほこりを取り除く。検出制御回路は変換されたパルス幅変調信号のデューティサイクルをリアルタイムで読み取る。モーターが正回転モードで動作しているとき、デューティサイクルに従い、検出制御回路は、ファンの回転速度を制御するモーターコントローラを駆動する。デューティサイクルが第１の閾値よりも小さいないし等しい場合、検出制御回路は正回転モードから逆回転モードへとモーターの動作状態を切り替えるモーターコントローラを駆動する。【選択図】なし |
