PROBLEM TO BE SOLVED: To provide an electric direct acting actuator that can save space, reduce costs and improve redundancy.SOLUTION: In an electric direct acting actuator 1, a direct acting mechanism 3 and an electric motor 2 are arranged side by side coaxially on the same shaft center acting as a shaft center of rotary input/output shaft 5 of the direct acting mechanism 3. The electric motor 2 comprises a stator 7 and a rotator 8 arranged so that a direction of a magnetic pole generating an interlinkage magnetic flux contributing to torque is in parallel to a motor rotation shaft. The rotator 8 has, on both surfaces in the shaft direction thereof, torque generation surfaces respectively. The stator 7 has first and second exciting mechanisms 7A and 7B which are arranged at both sides respectively in the shaft direction of the rotator 8. The first and second exciting mechanisms 7A and 7B have independent coils groups 11A and 11B of first and second systems, and is provided a power supply system 50 which supplies power to the coil groups 11A and 11B of the first and second systems independently from each other.SELECTED DRAWING: Figure 2

    【課題】省スペース化およびコスト低減を図ると共に、冗長性を向上させることができる電動式直動アクチュエータを提供する。【解決手段】この電動式直動アクチュエータ1は、直動機構3と電動モータ2とが、直動機構3の回転入出力軸5の軸心となる同一の軸心上に並んで配置され、電動モータ2は、トルクに寄与する鎖交磁束を発生する磁極の向きが、モータ回転軸と平行となるように配置された固定子7および回転子8を備える。回転子8は、この軸方向の両面にそれぞれトルク発生面を有する。固定子7は、回転子8の前記軸方向の両側にそれぞれ配置される第1,第2の励磁機構7A,7Bを有し、第1,第2の励磁機構7A,7Bは独立した第1,第2系統のコイル群11A,11Bを備え、第1,第2系統のコイル群11A,11Bにそれぞれ独立して電力を供給する電力供給系統50が設けられた。【選択図】図2
