—Product

Slots, windings, and nonlinear FEA

Four setup steps from geometry through bearing losses — then field maps and dq outputs.

Geometry screen with topology, slots, poles, and rotor skew

01Slots

Winding radial layout with double-layer coil pitch

02Winding

Coil slot packing with copper fill and phase resistance

03Coil

Setup losses with SKF bearing loss versus speed chart

04Setup

MMF space harmonics bar chart orders 1 through 30

MMF harmonics

Winding factor and space-harmonic audit before FEA.

Laminated steel core magnetization curve B(H) for M-19 grade

Steel BH curves

Assign laminations and magnet grades before the nonlinear solve.

Built for SPMSM design

Purpose-built C solver on iPhone, iPad, and Windows — one workflow from geometry to dq outputs.

Geometry

Slots, magnets, rotor skew — validated before meshing.

Analysis

|B| maps, waveforms, Ld/Lq, torque ripple, and efficiency.
