To provide a drive motor which can inhibit rapid rotation of an output shaft based on a backlash element of a spline joint, and to provide an electric vehicle.SOLUTION: In a drive motor 100, a torque sensor 50 is disposed at an outer periphery of a shaft. The drive motor 100 includes: a rotor 300; a rotor shaft 310 disposed in the rotor 300; and an output shaft 312 which is coupled to the rotor shaft 310 by a spline joint 314 and transmits rotational force of the rotor shaft 310 to an output side. The torque sensor 50 is disposed closer to the output side than the spline joint 314 in a range where the torque sensor 50 does not overlap with the spline joint 314.SELECTED DRAWING: Figure 3
【課題】スプライン継手のガタ要素に基づく出力シャフトの急速回転を抑制することができる駆動モータ及び電動車両を提供する。【解決手段】シャフトの外周にトルクセンサ50を配置した駆動モータ100であって、ロータ300と、ロータ300内に配置されるロータシャフト310と、ロータシャフト310とスプライン継手314によって結合され、ロータシャフト310の回転力を出力側に伝える出力シャフト312とを有し、トルクセンサ50は、スプライン継手314と重ならない範囲で、スプライン継手314よりも出力側に配置されている。【選択図】図3
