Electrical machine parameters

Constant Ld, Lq and magnet flux.

2D tables for Ld, Lq and magnet flux Id and Iq are dependent.

3D tables for phase inductance, magnet flux and torque tables Id Iq and θ are dependent.
Mechanical model

Basic inertia and friction mechanical model attached to the rotor. Users can define their own model on CPU or through customizing the FPGA
