Problems solved by technology
In the design process of many small and medium-sized coils, it is necessary to re-calculate and deduce the electromagnetic force, which is not only very troublesome, but also the obtained parameter values often lack the necessary practical test, which greatly reduces the accuracy of the parameters.

The invention discloses a device for automatically detecting electromagnetic parameters of an electromagnetic coil, which comprises a supporting and transmission mechanism, a coil card switching mechanism, a ball loading mechanism provided with a ball and an eddy current position sensor arranged at one side of the ball, and is characterized in that the supporting and transmission mechanism comprises a supporting mechanism and a transmission mechanism used for driving the ball loading mechanism to move up and down in a reciprocating manner, and the coil card switching mechanism and the ball loading mechanism respectively test a pressure change value in the process that the ball is attracted by the electromagnetic coil and generates a movement trend and collaborate with the eddy current position sensor which performs real-time monitoring on vibration of the ball so as to obtain a current value and a suspension clearance of the electromagnetic coil at the moment when the ball stays at a critical pressure point. The device not only meets requirements of electromagnetic parameter detection of the coil for the position and current information feedback accuracy, but also realizes rapid measurement for coil electromagnetic parameters of different coils, first-order current parameters of a single-degree-of-freedom electromagnetic suspension system and first-order position parameters ofthe single-degree-of-freedom electromagnetic suspension system on the basis.
Description
technical field [0001] The invention relates to the technical field of electromechanical integration, in particular to a device for automatically detecting electromagnetic parameters of electromagnetic coils. Background technique [0002] Traditional electromagnetic devices require only two states for the electromagnet: suction and non-suction. With the development of modern control theory and the continuous upgrading of electromagnetic devices, the electromagnetic force of electromagnets often needs to be accurately acquired and controlled. [0003] The electromagnetic parameters of electromagnetic coils (hereinafter referred to as coil electromagnetic parameters) are important indicators to measure the ability of electromagnetic coils to generate magnetic fields. This parameter plays an important role in the process of coil design, electromagnetic force calculation, and mathematical model establishment of electromagnetic systems. [0004] In the field of electromagnetics,...
