Embodiment Construction
[0012] As shown in the drawings, the control circuit of a bistable permanent magnet operating mechanism according to the present invention includes a permanent magnet operating mechanism and a pulse signal control circuit connected to the pulse coil of the permanent magnet operating mechanism. As shown in Figure 1, the housing 1 of the permanent magnet operating mechanism is provided with an output shaft 2, the output shaft 2 protrudes through the end caps 15 at both ends of the housing 1, the front end is connected with the actuator through a connecting pin, and the rear end is fixedly connected with end cap9. The materials of the shell 1 and the end cover 15 are all ferrous which is easy to conduct magnetism. The contact part between the output shaft 2 and the shell 1 is fitted with an anti-magnetic bushing, and the middle section of the output shaft 2 located inside the shell 1 is fixedly installed with an iron core 3, and the outer side of the iron core 3 is provided with ...
