| description | To provide a rotary tool capable of controlling overshoot by a control means making a motor accelerate to a target rotational frequency by switch-on.SOLUTION: A rotary tool comprises: a motor rotating a spindle; a fastener fastening a tip tool by screwing together with the spindle; a switch; a speed controller operational by operators and configurable in at least two target revolutions; and a control unit controlling the rotation/stop of the motor in response to switch operation and controlling rotation/stop of the motor in response to a switch operation to rotate the motor by a set-up target revolution. The control unit controls so that the motor revolution temporarily exceeds the target one in a process in which the motor is driven by the target revolution from start-up when the set-up target revolution is small, and controls the motor so that the excess amount of the revolution enlarges compared with when a set-up target revolution is large.SELECTED DRAWING: Figure 11
【課題】スイッチがオンされてモータを目標回転数まで加速させる制御におけるオーバーシュート量を調整することができる回転工具を提供する。【解決手段】スピンドルを回転させるモータと、スピンドルに螺合して先端工具を固定する固定具と、スイッチと、作業者が操作可能で少なくとも２つ以上の目標回転数を設定可能な速度調整装置と、スイッチの操作に応じてモータの回転・停止を制御し、設定された目標回転数でモータが回転するよう制御する制御装置を有する回転工具において、制御装置は、設定された目標回転数が小さい場合に、モータの起動からモータが目標回転数で駆動される過程においてモータの回転数が一時的に目標回転数を超えるように制御し、その回転数の超過量が設定された目標回転数が大きい場合と比較して大きくする。【選択図】図１１ |
