Title:
ELECTRIC ACTUATOR
Document Type and Number:
Japanese Patent JP2022056523
Kind Code:
A
Abstract:
To provide an electric actuator having a structure which can reduce the man-hour and the time required for assembly work of a rotation sensor.SOLUTION: An electric actuator 100 comprises: a motor 20; a transmission mechanism 30 which is coupled to one side in the axial direction of a motor shaft 21a; an output shaft 41 to which rotation of the motor shaft is transmitted via the transmission mechanism; a first rotation sensor 81 which can detect the rotation of the motor shaft; and a second rotation sensor 82 which can detect rotation of the output shaft. The motor shaft is a hollow shaft. The output shaft extends through the inside of the motor shaft to the other side in the axial direction. In a portion, of the motor shaft, located further on the other side than a rotor body 21b, there is provided a first detected part 24 whose rotation is detected by the first rotation sensor. In a portion, of the output shaft, located further on the other side than the motor shaft, there is provided a second detected part 45 whose rotation is detected by the second rotation sensor.SELECTED DRAWING: Figure 1
