Description
Technical Field

Background
The permanent magnet motor is provided with a permanent magnet on a rotor, and the permanent magnet is assembled by adopting a surface mounting mode or an interpolation mounting mode. When the surface type installation mode is adopted, the permanent magnet is attached to the outer circular surface of the rotor iron core, and when the internal insertion type installation mode is adopted, the permanent magnet is inserted into the interior of the rotor iron core. The permanent magnet can generate a magnetic field without an excitation magnetic field, so that the permanent magnet motor has the characteristics of high efficiency, high control precision, hard mechanical property and the like, and is increasingly widely applied.
The permanent magnet is assembled on the permanent magnet motor rotor in a front magnetizing assembly mode and a rear magnetizing assembly mode. The front magnetizing assembly means that the permanent magnet is magnetized and then assembled on the rotor, and the rear magnetizing assembly means that the permanent magnet is not magnetized and then the permanent magnet is magnetized after being assembled on the rotor. The post-magnetizing assembly is easy to assemble because the permanent magnet has no magnetism, but a special magnetizing machine is needed subsequently, the investment is large, and the post-magnetizing assembly is not suitable for motor models and series with more varieties. The pre-magnetizing assembly process is simple and is a common assembly mode at present. When the permanent magnets are assembled by using a pre-magnetizing assembly process, the polarities of the two adjacent permanent magnets need to be kept opposite, namely the permanent magnets are alternately arranged according to the N pole and the S pole. For the surface type installation mode, because the permanent magnet is exposed outside, the polarity of the permanent magnet can be determined by marking the N pole and the S pole in advance on the permanent magnet by a tester by observing the N pole and the S pole marks on the permanent magnet, so that polarity detection is realized, but the labor cost is greatly increased by marking the N pole and the S pole on the permanent magnet in advance, few manufacturers can adopt the mode, and the factory test is directly carried out after the whole motor is assembled. For the interpolation type installation mode, the permanent magnet is hidden in the rotor core, so that the detection cannot be carried out by marking an N pole and an S pole, the detection is not carried out after the transfer and the distribution are finished at present, and the delivery test is directly carried out after the complete machine of the motor is assembled.
At present, in order to improve the accuracy of permanent magnet assembly, motor manufacturers mainly adopt technical and skilled operators to assemble permanent magnet assembly stations. However, even the skilled operators can not avoid errors, once the permanent magnet is assembled incorrectly, the quality problem can be found only when the delivery test is carried out after the complete machine of the motor is assembled, and the rework cost is higher.
