To provide a door drive device by which, even during travel of a railway vehicle, doors can be closed without stopping the railway vehicle.SOLUTION: A door drive device 1 of a railway vehicle having a motor 131 to generate a rotational power by a drive current flowing into three-phase coils 131U, 131V and 131W, and doors to be opened/closed based on the rotational power, comprises: drive current generation parts 3, 5 and 6 to make a drive current flow into coils of phases different between at the time of open-driving the door and at the time of close-driviing the door in response to rotational position data H1, H2 and H3 of a rotor of the motor 131; and a restriction circuit 4 to restrict a drive current not to flow into coils of phases through which the drive current should be flown at the time of open-driving, based on an FSR signal indicating that the railway vehicle is in a traveling state and the rotational position data H1, H2 and H3.SELECTED DRAWING: Figure 2

    【課題】鉄道車両が走行中であっても停車させることなく扉を閉駆動できる扉駆動装置を提供する。【解決手段】3相のコイル131U、131V、131Wに流される駆動電流により回転動力を発生させるモータ131と、回転動力に基づき開閉駆動される扉とを有する鉄道車両の扉駆動装置1は、モータ131の回転子の回転位置データH1、H2、H3に応じて、扉の開駆動時と閉駆動時で異なる相のコイルに駆動電流を流す駆動電流生成部3、5、6と、鉄道車両が走行状態にあることを示すFSR信号と回転位置データH1、H2、H3とに基づき、開駆動時に駆動電流を流すべき相のコイルに、当該駆動電流が流れないように規制する規制回路4とを備える。【選択図】図2
