The Effect of Magnet Structure Size on Halbach Array

Ai‐Jun Wang

Open publisher page 1 citations

Abstract

Based on the basic model of the permanent motor with the inside rotor of Halbach magnet array structure,compare Halbach magnet structure with ordinary magnetic pole of the permanent magnet motor.The air-gap flux density distribution of Halbach magnet structure has been analyzed to get the air-gap flux density of the magnet structure,changing laws of the flux with the thickness of the permanent magnet.It shows that Halbach array has characteristic of magnetic single side and fine sine characteristic.
