[0038] see figure 1 , which is a flow chart of a method for controlling a locked-rotor fault of an electric actuator provided in the first embodiment of the present invention. The method for controlling the stalled fault of the electric actuator specifically includes:
[0039] Step S10, obtaining the actual rotation angle information of the valve;
[0040] It should be noted that acquiring the actual rotation angle information of the valve here may be checking the actual rotation angle information of the valve each time the valve rotates, or obtaining the actual rotation angle information of the valve periodically.
[0041] Step S20, judging whether the absolute value of the absolute value of the difference between the actual valve rotation angle α1 and the valve rotation command angle α2 is greater than the preset difference β;
[0042] It should be noted that the actual valve rotation angle α1 here is the actual rotation angle of the valve under the control of the rotating...

[0065] see image 3 , the embodiment of the present invention also provides an electric actuator stall fault detection device 100 . Wherein, the electric actuator stall fault detection device 100 includes, for example: an acquisition module 110 for acquiring the actual rotation angle information of the valve, the valve rotation information and the stall information; an angle monitoring module 120 for detecting the angle of the valve rotation; The control module 130 is used to control the valve to realize the electrical protection mode and / or the self-cleaning mode.
[0066] In a specific embodiment, the acquisition module 110, the angle monitoring module 120, and the control module 130 of the electric actuator stall fault detection device 100 cooperate to implement the electric actuator stall fault control method described in the first embodiment above, here I won't repeat them here.
