Summary:PROBLEM TO BE SOLVED: To provide a technology which can downsize an axial dimension of a motor, with regard to the motor using a sensor.SOLUTION: A motor having a rotor including a permanent magnet 56 and a stator 34 around which a coil 60 is wound has a sensor 42 for detecting a rotation position of the rotor by detecting a magnetic flux of the permanent magnet 56. The sensor 42 faces an axial end surface of the permanent magnet 56 and is arranged inside a coil end 60a of the coil 60 in a radial direction.SELECTED DRAWING: Figure 2 【課題】センサを用いるモータに関して、その軸方向寸法の小型化を図れる技術を提供する。【解決手段】永久磁石５６を有するロータと、コイル６０が巻き回されたステータ３４とを備えるモータであって、永久磁石５６の磁束を検知することでロータの回転位置を検出するためのセンサ４２を備え、センサ４２は、永久磁石５６の軸方向端面と対向し、かつ、コイル６０のコイルエンド６０ａの径方向内側に配置されることを特徴とするモータである。【選択図】図２
