Abstract: A state determination device determines a state of a paint device including an air motor that rotates by a supply of a gas, a rotational shaft that serves as a rotational center of the air motor, and a rotary atomizer head that is connected to the rotational shaft and sprays paint. The paint device further includes a vibration detection unit that detects a vibration of the paint device, and the state determination device includes a frequency component acquisition unit and an abnormality determination unit. The frequency component acquisition unit acquires a frequency component caused by a contact between the rotational shaft and the air motor from a detection result by the vibration detection unit. The abnormality determination unit determines whether an abnormality of the air motor exists or not based on an acquisition result by the frequency component acquisition unit.
