ROTARY MACHINE DEVICE AND LINEAR MACHINE DEVICE

A rotary machine device configured to contact with an external object is provided. The rotary machine device includes a rotary motor, a first encoder, a fixed housing, a fixed shaft, an output shaft and a second encoder. The rotary motor includes a motor housing and an exerting shaft. As the rotor of the motor housing rotates for a rotation angle, the rotor drives the exerting shaft to rotate for an exerting angle. The first encoder detects the rotation angle of the rotor. The output shaft includes an elastomer and is inserted in an accommodation hole of the fixed shaft. The elastomer is penetrated through the output shaft and is connected to the exerting shaft. The second encoder includes a disk and a sensor disposed on the exerting shaft and the fixed shaft respectively. The sensor detects the exerting angle of the exerting shaft through the disk.
