Magnetic field analysis of an axially magnetized tubular permanent magnet linear motor
摘要
Abstract
Aiming at the problem of the air⁃gap magnetic field distribution and calculation of the axially magnetized tubular permanent magnet linear motor(TPMLM), which is very different from the radially magnetized tubular per⁃manent magnet linear motor, a new analytic method of calculating air⁃gap magnetic field of the axially magnetized TPMLM was proposed for this paper, which was based on the basic air⁃gap magnetic field. This tool had calculated the basic air⁃gap magnetic field intensity of the slotless and slotted structure by using the Schwarz⁃Christoffel meth⁃od. And the air⁃gap magnetic field intensity of the motor was derived from the calculation of the magnetic field in⁃tensity at the minimum air⁃gap. A 10⁃pole 9⁃slot axially magnetized TPMLM was studied to verify the validity and accuracy of the proposed method. The results showed that the peaks of the air⁃gap magnetic field calculated by the analytical method and finite element method were 1.3 T and 1.28 T. The variation principle of the air⁃gap magnetic field obtained from the two methods above had the same trends. The two results were in good agreement. The pro⁃posed method for calculating motor magnetic field is proven to be quick, effective, and accurate.关键词
