摘要
The eddy current loss in the thrust rod of an iron-cored, 2-phase, tubular permanent magnet brushless motor is investigated by time-stepped transient finite element analysis. It is shown that the dominant cause of the loss is the permeance modulation which results from the teeth in the laminated thrust block, whose spacing is the same as the magnet pole-pitch. Loss predictions are validated by measurements.
