Sinusoidal FOC Control of Brushless Motor - Open Loop

Another #shorts about a future video tutorial on FOC control using SPWM signals from the Arduino to create sinusoidal waves and change the orientation of the magnetic field and rotate the brushless motor very slow and precise

It's beautiful to see those PWM signals rolling like that.

a really cool thing i saw is using a bldc with position feedbach as a knob with force feedback

[MehmetSutas]

Very excited. Looking forward this video, schematic and code. 😍

[ramarastogi]

Thing I've been withing for months

[soonlor]

Im excited to wait the explanation video

[Agni_Puthra]

Looking forward. Would like to know more about what is FOC. 👍

Hey I have been a fan of your open source projects, is it possible to make a open source inkject printer ? With readily available parts like Arduino and stepper motor driver and probably adapting a off the shelf printer cartridge, but refillable may be.

Please connect the GND of the scope probes next time!

You can't use this wave form for high current applications. You need your own dead time control over pwm signals for h bridges. Esp32 has 2 6 output h bridges gave me wanderful results to generate 3 phase sinusoidal voltage of with 8 bit amplitude sample at 20 khz pwm frequency.

Sir can you share this code?
I'm working on the FOC based BLDC controller. I'm already try your ESC also

[vishnupi]

Hi. Its very nice. Can you share the code please?

[mashhoodh]

Where should i connect the probes to get the PWM?

[hamidsk]

Is swpm better than trapezoidal switching?
How about programing point of view as spwm need more cpu resources

[Chazz]

How much torque is there at slow speeds?

[cruzemissile]

can you use a system like this to control three microwave transformers stepped down for high current output ?

Hello my friends, that's really cool.

This is awesome, if you could make this in such a way that its closed loop and able to drive a larger motor using a power mosfet inverter it could be used to drive ebikes. Atleast the control board section by arduino would be nice. We at our company use dsPIC33 mc for these purpose but it requires an icd kit and the PIC ecosystem is expensive for me.

Esp32 have an integrated motor control pwm that can do space vector control have you tried it?

[power-max]

It isn't really field oriented control, your just sending SPWM voltages to the 3 phases and the motor is snapping to align with the generated RMF. The angle ends up being zero under no torque load and if the angle gets too high (higher than 90° spinning too fast or too heavy a load) then it slips (de-syncs) and potentially stops rotating with the field due to the inertia and load.

[power-max]

SPWM, eww! You should use space vector modulation and 3rd harmonic injection! This let's you feed in a larger percentage of your DC bus to your motor, allowing it to spin slightly faster at a given DC input voltage.

This is not FOC it's a sinosodial control in open loop
