Permanent-magnet-less machine having an enclosed air gap
A synchronous system generates high power density at a high torque to weight ratio. some of these brushless slip-ring-less constructions have a reduced size, lower weights when without permanent magnets. A permanent magnet-less, brushless synchronous system includes a stator that generates a magnetic rotating field when sourced by an alternating current.A rotor disposed within the magnetic rotating field is placed away from the stator to form an air gap relative to an axis of rot ....etc

Simple Non-Linear Magnetic Analysis for Permanent-Magnet Motors


The need

In the process of designing a new motor/generator;
Method of Finite Element Analysis is used

The disadvantage - Computing time

Alternate option Nonlinear Magnetic Analysis on an equivalent magnetic circuit of the whole machine

Because of Magnetic Saturation in Stator teeth, the analysis becomes Nonlinear.

The procedure

The permeance values of the saturable permeance
tips are calc ....etc
