...Even though it has become relatively easy to design and manufacture PCBs and create our own hardware solutions for driving BLDC motors the proper low-cost solutions are yet to come. One of the reasons for this is the apparent complexity of writing the BLDC driving algorithms, Field oriented control (FOC) being an example of one of the most efficient ones. The solutions that can be found online are almost exclusively very specific for certain hardware configurations and the microcontroller architecture used. Additionally, most of the efforts at this moment are still channeled towards the high-power applications of the BLDC motors and proper low-cost FOC.

...Using a statistically robust sample across multiple filters with precise focus values (–2.0 to +2.0 µm), we quantify: (1) focus-dependent FWHM variations of 18.7% across the operational range, following a parabolic relationship with minimum at focus =–0.2 µm (FWHM(focus) = 1.92 + 0.031·foc
