    project on bldc motor

    BLDC motor has few sources of torque ripple related with motor itself or control. Which type of sources you plan to minimize?

    Field Oriented Control

    More basic info regarding FOC you may find from Motion control university inside PMD Inc website - http://www.pmdcorp.com/news/articles.cfm, especially "New Developments in Commutation and Motor Control Techniques" and "Mathematics of Electronic Motor Control" both regarded FOC details...

    Looking for software to develope a control app

    Galil motion controllers have CAD-to-DMC software allowing translate *.dxf or other AutoCAD files to internal controller's commands directly.

    inertia ratio of servo

    The inertia ratio (or inertia mismatch) is must be taken into account for servo with low mechanical stiffness. Tuning of servo is often difficult due to mechanical resonance in this case. It's true for both high (more than 1:5) and low (less 1:0.5) inertia mismatches.

    single phase output encoder

    Such type encoder doesn't allow you to define direction of rotation that is possible with two encoder's channels only. And because that it intends for speed control only.

    What is the sin-cos encoder phase angle?

    Which format of output have your encoder? I.e. digital (A,B quad), analog (1V)... ??

    Load cell millivolt signal conditioner

    Of course load cell isn't connected to PLC directly. Except Strain Gauge Transmitter with outputs 0-5V or 0-10V, check if your PLC has an Analog Input module with load cell option.
