Document Type and Number:
WIPO Patent Application WO/2020/095535
Kind Code:
A1
Abstract:
A motor according to an embodiment of the present invention is provided with a shaft (104), a rotor (103), a member (116), and a sensor (117). The rotor (103) is rotatably supported by the shaft (104). The member (116) faces the rotor (103) in the axial direction of the shaft (104). The sensor (117) is provided to the member (116). The sensor (117) has a light source for radiating light in a radial direction, and has a light receiving section for receiving the light radiated from the light source. The rotor (103) has a light blocking section (105a) formed at an end of the rotor (103) in the axial direction. During the rotation of the rotor (103), light propagating from the light source toward the light receiving section is blocked by the light blocking section (105a).
