ELECTRIC VALVE CONTROL DEVICE, ELECTRIC VALVE DEVICE, AND ELECTRIC VALVE CONTROL METHOD

Provided are an electrically operated valve control device, an electrically operated valve device, and a method for controlling an electrically operated valve, wherein the time required for the initialization operation of the electrically operated valve can be shortened and noise can be suppressed. The electric valve control device (70) supplies a drive current to the stator (60) and rotates the rotor (41) in a first direction. Voltage generated in the stator (60) due to rotation of the rotor (41) is acquired. Then, on the basis of at least one of the following conditions, whether the electric valve (5) is in a rotation limiting state in which the rotation of the rotor (41) in the first direction is limited by the stopper mechanism (49): the area of the waveform of the voltage, and the amplitude of the wave periodically observed in the waveform of the voltage; and periodic occurrence of new waves different from waves observed periodically in the waveform of the voltage. 提供一种能够缩短电动阀的初始化动作所需的时间并抑制噪声的电动阀控制装置、电动阀
