Problems solved by technology

[0005] One of the purposes of the present invention is to overcome the defects of large current and temperature rise of the traditional ordinary DC electromagnet in the prior art when maintaining the state, and to provide a low-temperature rise electromagnet. The second purpose is to provide a more traditional 24V electromagnet. The electromagnet starts the electromagnet with large thrust and low temperature rise. The third purpose is to provide a technical solution for replacing the large-diameter electromagnet with a small-diameter electromagnet.

Abstract

The invention discloses a low-temperature-rise great-thrust direct current electromagnet, and belongs to the technical field of an electric control valve element. The electromagnet comprises a direct current power supply input end, a coil, an armature and an iron core, wherein a positive electrode of the power supply is connected to an input electrode of the coil, an MOS (metal oxide semiconductor) field-effect tube is connected between an output electrode of the coil and a negative electrode of the power supply, a broken triode Q1 provides triggering voltage for the MOS field-effect tube, and the triode is intermittently conducted and cut off, so that the MOS filed-effect tube works in an on-off state, voltage exerted at the two ends of the coil is pulse with a certain duty ratio, and the current of the coil in the armature maintaining state is lower than the current during the electromagnet starting. The low-temperature-rise great-thrust direct current electromagnet can achieve the great-thrust low-temperature-rise effects of the electromagnet.

Description

technical field [0001] The invention relates to an electromagnet, in particular to a low-temperature rising high-thrust DC electromagnet, which belongs to the technical field of electric control valve components. Background technique [0002] When the traditional ordinary DC electromagnet is in use, when it is energized and opened, the valve core is often stuck, inflexible or the thrust of the electromagnet is insufficient, causing the valve core to not move and causing abnormal movement. When closing, the thrust is large and there is unnecessary power consumption. , resulting in a high temperature rise. When the electromagnet is just turned on to do work, the thrust is small due to the large air gap. , although no work is done, there is still the same large current as when it is opened to maintain the thrust. For the force, the force at the closing point is too much, resulting in high temperature rise and large power consumption during use. [0003] Due to the restriction ...
