Magnetizing Method for the Post-Assembly Magnetization of A Hermetic DC Compressor

摘要

A new magnetizing method for the design of post-assembly for a hermetic DC compressor is presented. Assembly of a permanent magnet rotor into the stator core where the permanent magnets have previously been magnetized is a difficult operation. The utility of this approach for the post-assembly magnetization will be-demonstrated by a case study, which will use a 4 poles interior permanent magnet motor as a sample of magnetization, and also the predicted performance of the example motor will be validated by experiment.
