[0002] At present, during the assembly process of the magnetic steel plug-in motor rotor, the magnetic steel needs to be inserted into the magnetic steel groove of the rotor iron core according to the preset magnetic pole direction, so the magnetic steel magnetic pole needs to be detected before assembly, and then inserted. However, it still happens from time to time that the magnetic steel is inserted in the wrong direction. Once a mistake occurs, the entire rotor will not work properly.

Embodiment Construction
[0020] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0021] like Figure 1 to Figure 6 As shown, a magnetic steel plug-in error correction method includes the following steps:
[0022] 1) Fixing tooling: fix the magnetic steel inserting tooling 1 on the rotor core 21, so that the guide groove 12 on the magnetic steel inserting tooling 1 and the magnetic steel slot 24 on the rotor core 21 are facing each other;
[0023] 2) Test and error correction: Test the magnetic steel 31 close to the guide groove 12 according to the insertion direction. The upper part of the guide groove 12 is provided with a detection magnetic strip 14 at an angle of 5° to 85° with the depth direction of the guide groove 12. In this embodiment The angle β between the detection magnetic strip 14 and the depth direction of the guide groove 12 is 45°, other angles within the range such as 30°, 60°, and 72° can also be detected, and the detec...

The invention discloses a magnetic steel inserting and mounting error correction method. The magnetic steel inserting and mounting error correction method comprises the following steps of 1) tool fixing: enabling a magnetic steel inserting and mounting tool to be fixed on a rotor iron core, and enabling a guiding groove in the magnetic steel inserting and mounting tool to be aligned to a magneticsteel groove in the rotor iron core; 2) performing test error correction: enabling magnetic steel to be close to the guiding groove in the insertion direction to be tested, wherein a detection magnetic strip with an included angle of 5-85 degrees with the depth direction of the guiding groove is arranged on the upper part of the guiding groove, and the magnetic pole direction of the detection magnetic strip is opposite to the preset magnetic pole direction of the magnetic steel; if the magnetic steel is attracted, proving that the magnetic steel insertion direction is correct, if the magneticsteel is repelled, proving that the magnetic steel insertion direction wrong, and completing magnetic steel inserting and mounting test error correction. By virtue of the method, magnetic steel insertion accuracy can be ensured, and rotor magnetic steel assembling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a magnetic steel insertion error correction method. Background technique [0002] At present, during the assembly process of the magnetic steel plug-in motor rotor, the magnetic steel needs to be inserted into the magnetic steel groove of the rotor iron core according to the preset magnetic pole direction, so the magnetic steel magnetic pole needs to be detected before assembly, and then inserted. However, the situation that the magnetic steel is inserted in the wrong direction still occurs from time to time. Once a mistake occurs, the entire rotor cannot work normally. [0003] Therefore, those skilled in the art are devoting themselves to developing a magnetic steel insertion error correction method that can find out whether the magnetic steel is inserted correctly before the magnetic steel is inserted. Contents of the invention [0004] In view of the above-mentioned defects...
