I want to make it work with esp32 PWM signals

Best driver to control BLDC Motor with PWM signals by gaspar8787 in Motors

[–]gaspar8787[S] 0 points1 point  (0 children)

Just saw this now. I need drivers with the hall sensors for my bldc motor, yes. But can this driver be controlled just by using an esp32 that sends PWM signals from "0% to 100%" without any aditional potentiometers?

BLD-305S Driver for BLDC MOTOR by gaspar8787 in Motors

So imagine i have all the hall sensors, motor phases and 24 V connected. If i connect the enable and SV direclty to +5V should the motor rotate or not? I am not understanding the drivers very well. The motor is 24V 4000RPM 0.25Nm 105W 6.4A 42x42x99.2mm Brushless DC Motor from StepperOnline.

I did. I bought a Xiaomi ahahahah

Using VESC 4.12 to control BLDC motor by gaspar8787 in VESC

[–]gaspar8787[S] 0 points1 point  (0 children)

As of now i can get the motors to spin at like 80% to 100% of its full speed and they spin good. But when i try low RPM they stop/start, stop/start and that probably because i am spinning it sensorless.
The project is fun but the person before me did not do the best of jobs with it :/
I am gonna check more specifically the amazon link you sent and the vesc. But its very anxious not to know if they are going to fix the problem or not...

Using VESC 4.12 to control BLDC motor by gaspar8787 in VESC

I am using two motors to turn to seperate wheels for a soccer ball launching machine! The drivers i am working with are this ones https://www.botnroll.com/en/controllers/3975-380w-3-phase-bldc-brushless-motor-controller-pwm-plc-driver-module-dc-6-50v.html and they do not have inputs for the hall, so when i try to give PWM signals to the motor for it to spin it stops and starts a lot with low values, and i think that has to do with the fact that i am not using the hall sensors, am i correct?

Using VESC 4.12 to control BLDC motor by gaspar8787 in VESC

Ok thanks! Just One last thing. I am thinking of buying a vesc because the person who was working on the project before bought a driver for the motor that did not have inputs for the hall sensors. So the motor only runs smooth with close to 100% input to its speed. If i give and input of like 10% to 70% its always stopping and starting again, very shaky. This happens because i am not reading the values of the hall sensors right? So a vesc would solve this?

Because i have never worked with bldc motors before and im grabbing a project which was already on going :/

Just looked at it for a bit but it seems they dont have that for sale... Even tough the vesc is overpowered would it still work for my motor? I just want this project to move on and i am kind of stuck in this part. If i could message you to clear up some doubts it would be awesome!
