PROBLEM TO BE SOLVED: To provide a motor that can be downsized while incorporating an angle sensor, an in-wheel motor and a wheel device.SOLUTION: A motor according to the embodiment comprises: a stator; a rotor rotating relative to the stator around a rotary shaft; a shaft arranged so as to extend in an axial direction of the rotary shaft; and an angle sensor for detecting a rotation angle of the rotor with respect to the stator. The shaft is fixed to one of the stator and the rotor and arranged so as to face the other of the stator and the rotor with a predetermined distance in the axial direction. The angle sensor is arranged between an end part of the shaft in the axial direction and a portion of the other of the stator and the rotor, which faces the end part.SELECTED DRAWING: Figure 7 【課題】角度センサーを内蔵しつつ、小型化が可能なモータ、インホイールモータ及び車輪装置を提供すること。【解決手段】実施形態に係るモータは、ステータと、回転軸を中心として前記ステータに対して相対的に回転するロータと、前記回転軸の軸方向に延在するように配置されたシャフトと、前記ステータに対する前記ロータの回転角度を検出する角度センサーとを備え、前記シャフトは、前記ステータ及び前記ロータの一方に固定され、前記ステータ及び前記ロータの他方と前記軸方向に所定の距離だけ離間して対向するように配置され、前記角度センサーは、前記シャフトにおける前記軸方向の端部と、前記ステータ及び前記ロータの他方における前記端部と対向する部分との間に配置される。【選択図】図７
