Abstract

The invention relates to a method for screening iron cores of an electromagnetic gyroscope. The method at least comprises a detection circuit (15) and a shell (16), wherein a to-be-tested iron core inserting hole (3) and a standard iron core inserting hole (4) are arranged on the shell (16), the to-be-tested iron core inserting hole (3) and the standard iron core inserting hole (4) are electrically connected with the detection circuit (15), a standard iron core is inserted into the standard iron core inserting hole (4) on a panel, a to-be-tested iron core is inserted into the to-be-tested iron core inserting hole (3) on the panel, and the detection circuit (15) can directly display the difference value between the to-be-tested iron core and the standard iron core on a meter (1). According to the screening method, the magnetic iron cores with certain difference and within the tolerance range can be rapidly screened and classified, thereby improving the precision of electromagnetism balance of the gyroscope, greatly reducing the procedures of multi-time repeated debugging and multi-time replacement of the iron cores and reducing the labor intensity of an operator.

Description

technical field

[0001] The invention relates to a method for screening electromagnetic gyroscope cores. Background technique

[0002] In the electromagnetic gyroscope, maintaining the electromagnetic balance is the basis of the electromagnetic gyroscope's work. Generally, the symmetrically installed iron core is the basic guarantee for maintaining the electromagnetic balance of the gyroscope. Therefore, the iron core is a very important part of the electromagnetic gyroscope. Therefore, it is required that the magnetic flux of a group (four) iron cores installed in the same gyroscope should be basically the same.

[0003] According to the theory of electromagnetic balance, only under the condition of P1=P2=P3=P4 can the electromagnetic field be kept in balance and the spinning gyroscope can keep running stably. In order to ensure the balance accuracy of the electromagnetic field, the difference in magnetic flux of the four iron cores installed in the same gyroscope must be c...
