Zusammenfassung: | [Object] To provide an electric valve control device capable of reducing a duration of an initialization operation for an electric valve and suppressing noise, an electric valve device, and a method for controlling the electric valve.[Solution] An electric valve control device (70) inputs a pulse to a stepping motor (66) to rotate a rotor (41) in a first direction. The electric valve control device (70) obtains a voltage generated in a stator (60) by rotation of the rotor 41. The electric valve control device (70) determines whether an electric valve (5) is in a first-rotation restricted state where the rotation of the rotor (41) in the first direction is restricted, based on a degree of difference between a waveform of the voltage and a reference waveform of the voltage. |
