Hi,
I need example of sinusoidal control (SPWM) with piccolo.
I searched it in the controlSUITE folder.
But only FOC and trapezoidal examples are in folder.
Can I get the example of SPWM with piccolo?
I believe you may be confused. BLDC (BrushLess DC) motors require trapezoidal waveforms. Where-as Brushless AC, also known as Permanent Magnet Synchronous Machine (PMSM), require sine-waves.
FOC, means Field-Oriented Control or vector control which usually means it uses space-vector techiques.
SPWM can either mean sinusoidal or space-vector PWM depending on the literature you were taught from, Sinusoidal PWM usually refers to analogue methods of creating the PWM signals using sinusoids, triangle waves and comparators, comparisons are often made between Sin-PWM and space-vector, however space vector uses maths and the rotor angle to determine the switching sequence.
Do you really mean Sinusoidal as you are asking about BLDC motors?
The FOC solutions will have an SVPWM method that the motor sees as a pure sine wave.
What is your application? If you have a need for a sine wave but don't necessarily need all the benefits of pure FOC we have an MCU solution we will release later this summer that may be a fit.
Thank you for kind explanation.
