To provide a motor-driven direct-acting actuator and a motor-driven brake device which allow for space-saving high output motor control by down-sizing an electric motor.SOLUTION: A motor-driven direct-acting actuator DA includes an electric motor 4, a direct-acting mechanism 6 for converting rotation of the electric motor 4 into straight movement of a direct-acting part, and a control arrangement 2 for controlling the electric motor 4. The control arrangement 2 has an angular speed estimation function part 20b for estimating the angular speed of the electric motor 4, a current limit function part 23a limiting the current for energizing the electric motor 4 to a predetermined maximum, and a maximum current adjustment function part 24 for increasing the maximum value of the current limited by the current limit function part 23a, when the angular speed estimated in the angular speed estimation function part 20b becomes larger than the predetermined angular speed.SELECTED DRAWING: Figure 2

    【課題】電動モータの小型化を図り、省スペースで高出力なモータ制御を行うことが可能となる電動式直動アクチュエータおよび電動ブレーキ装置を提供する。【解決手段】この発明の電動式直動アクチュエータDAは、電動モータ4と、この電動モータ4の回転運動を直動部の直進運動に変換する直動機構6と、電動モータ4を制御する制御装置2とを備える。制御装置2は、電動モータ4の角速度を推定する角速度推定機能部20bと、電動モータ4に通電する電流を定められた最大値に制限する電流制限機能部23aと、角速度推定機能部20bで推定された角速度が定められた角速度よりも大きくなると、電流制限機能部23aによって制限する電流の最大値を増加させる最大電流調整機能部24とを有する。【選択図】図2
