電動機の速度検出装置。 In a traction motor for a vehicle, treated surfaces that produce different amounts of light reflection are alternately provided on the outer periphery of the joint of the motor, and light is transmitted at a position facing the treated surface of the joint. A speed of a main electric motor for a vehicle, characterized in that an optical fiber sensor having a light receiving part is disposed, and the speed is detected by detecting changes caused by the rotation of the processing surface based on the amount of reflected light. Detection device.
