Problems solved by technology

[0002] An electromagnet is a device that generates electromagnetism when it is energized. It is composed of a coil and a magnetically conductive material. The electromagnet is magnetic when it is energized, and the magnetism disappears after the power is turned off. Electromagnets are widely used in our daily life. The invention of the invention has also greatly improved the power of the generator; when using it, it is necessary to know the value of the attraction force and displacement of the electromagnet, which is often obtained through calculation, and the calculation is very complicated; it is necessary to design a method for the attraction force and displacement of the electromagnet. The test device is required to be able to measure the displacement while measuring the suction force. At present, there is no such linkage test device

Abstract

The invention discloses a testing device of electromagnet attraction force and motion displacement. The testing device comprises a foundation frame, a motive spindle, a displacement measuring assemblyand a gravity assembly; a through hole is formed in the center of the foundation frame, one end of the motive spindle is connected with an armature of a tested electromagnet, and the other end of themotive spindle penetrates through the foundation frame to be connected with the gravity assembly; the motive spindle can axially move along the tested electromagnet; the displacement measuring assembly comprises a fixed shaft sleeve and a movable shaft sleeve; scale lines are arranged on the outer circumferential faces of the fixed shaft sleeve and the movable shaft sleeve correspondingly; the fixed shaft sleeve movably sleeves the outer side of the motive spindle and is fixedly connected with the foundation frame; the movable shaft sleeve sleeves the motive spindle, and the bottom of the movable shaft sleeve is arranged on the outer side of the fixed shaft sleeve; and the tested electromagnet is arranged on the foundation frame. By adopting the testing device, the numerical value of theelectromagnet attraction force can be accurately obtained by increasing and decreasing weights, and meanwhile the magnitude of the motion displacement of the armature under the effect of the electromagnet attraction force can be read out intuitively.
