Description
パルスモータの相数は、3相以上であっても良い。
また、パルスモータは、リニアアクチュエータを構成するものに限らない。
脱調検出装置の機能を、マイクロコンピュータのソフトウェアにより実現しても良い。
Claims (1)
- 多相パルスモータの各相巻線に通電を行う駆動回路と、上位制御装置より入力される回転方向指令に応じて、前記駆動回路に前記通電制御指令を出力する制御回路とを備えてなる既存の多相パルスモータ駆動装置に接続されるもので、
前記巻線に通電される電流を検出する電流検出手段と、
前記電流の波形に脈流が発生したことを検出すると、脱調検出信号を前記上位制御装置に出力する脱調検出手段とを備え、
前記脱調検出手段は、
前記各相電流の2乗和を演算する演算手段と、
前記演算の結果が所定の閾値を上回ると、前記脈流の発生を検出して前記脱調検出信号を出力する判定手段とを備える多相パルスモータの脱調検出装置。
