Motor-Optimization
FEMM and MATLAB based parameterized motor geometry simulation
Geometry parameterization works for inrunners, outrunners, concentrated windings, distributed/full pitch windings.
Features so far:
- Draws a section of the motor based on ~15 geometry parameters, with the rotor at a specified angle (init_geometry_2.m)
- Calculates torque (static) given specified d and q axis currents (assming 1 turn per slot) or current density (calc_torque.m)
- Calculates stator/rotor mass, rotor inertia, phase resistance, resistive losses (calc_phys_props.m)
- Optimization with matlab's fmincon - doesn't work very well, the problem is full of local minima
- Monte-Carlo optimization - Looks very promising, perfect for plotting performance Pareto fronts to evaluate many possible designs
Features to add:
- IPM rotor suport, maybe
- inductance calculations
- line voltage calculations
- losses at speed, maybe eventually
