Brushless Permanent Magnet Motor (BLPMM) Modeling

This repository contains a modeling script for simulating the behavior and performance of a Brushless Permanent Magnet Motor (BLPMM), based on concepts and equations from the reference document:

Brushless Permanent Magnet Motor Design (v2) - Avislab

📘 Reference

The PDF by Avislab provides a comprehensive overview of the design process for a BLPMM, including:

• Motor geometry (rotor/stator dimensions, air gap, etc.)
• Magnetic circuit modeling
• Slot and winding design
• Back EMF calculation
• Torque estimation
• Finite element method (FEM) approximations
