The invention discloses a direct-current self-resetting electromagnet and relates to the technical field of electromagnets. The direct-current self-resetting electromagnet comprises a shell, photoelectric sensors, an electromagnet body, a movable iron core and a displacement detection plate, wherein the photoelectric sensors, the electromagnet body, the movable iron core and the displacement detection are installed in the shell. The movable iron core is installed in a shaft hole of the electromagnet body in a sleeved mode. One end of the movable iron core is connected to the displacement detection plate, and the other end of the movable iron core is connected with an abrasion-resistant lock cylinder. A reset spring is arranged between the movable iron core and the electromagnet body. The two photoelectric sensors opposite in position are further arranged on one side of the electromagnet body. The photoelectric sensors in different positions are matched with the displacement detection plate at different moments and are used for sensing the relative position of the displacement detection plate. According to the direct-current self-resetting electromagnet, modular design is taken as the principal thing, and the reaction time of sensing equipment is shortened; and in addition, a sensing device is improved, control is achieved through photoelectric sensing, and thus the reliability of sensing can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of electromagnets, in particular to a DC self-resetting electromagnet. Background technique [0002] Electromagnets generate magnetic force through current and then generate motion. They are mostly used in environments that require current to maintain a mechanical state or generate mechanical motion. For example, electromagnets are used to realize the opening and closing of electromagnetic locks. It is widely used in mechanical, electrical, and industrial production. and other fields have a wide range of applications. For example, the Chinese utility model patent "Return Spring Built-in Oil Stop Electromagnet", the application number is 201520131304.1, discloses that it includes a shell, a coil assembly and an iron core. The left end of the coil assembly is provided with a front cover, and the right end is provided with a rear cover. It consists of a pull-in coil and a hold-up coil wound on the bobbin. The ...
