I appreciate your effort and time my understanding with regards to esc and brushless (even brushed) motors has gone from zero to actually understanding their operation. You have sparked a desire to start a journey down this deep rabbit hole. Thank you kind sir you are a true gentleman an intelligent gentleman at that.

Thank you for sharing such an intense knowledge. One improvement I can suggest is an SPI port on the board for reading the magnetic encoder sensor for having full control over the motor.

@artbyrobot1 2 місяці тому

if the zero cross bemf already tells you exactly where the rotation of the motor is, then magnetic encoder offers ZERO additional information your code does not already know and is therefore a total waste and can be removed from the motor and tossed into garbage.

Some ideas for your ESC: This points improve efficiency because you are limiting losses in the body diodes of the FETs - the current will circulate in the active phases even with the PWM being in the low state, phase windings are inductors. 1. Don't switch the ground leg - not needed, will give you better efficiency to just have the ground leg connected for the whole commutation step. 2. Complementary switching of the high leg - if you will switch from the high fet to the ground fet with the PWM signal you will get higher efficiency. This point would add protection for the motor. 3. You can add low side current sensing for the whole inverter, no need to have current sensing of individual phases with 6 step commutation - can help to protect the motor if you set a maximum allowed current for example, can allow you to add a current controler instead of directly sending PWM signal to the FETs for desired power. This points would allow to use the controler for motion control. 4. Close the speed loop - measure the time of commutation, have a PI controler send current command to the current controler - allows to keep a stable motor speed - you could use the motor as a router spindle for example. 5. Close the position loop - add an encoder to the motor, have a PI controler send speed command to the speed controler - allows to keep the motor in a stable position - you could use the motor to power the movement axis in a router.

Dear electronoob :) very good podcast congrats! I have some question about the motor you are using, it is BLDC BRD6368 280KV 6-12S , that was used also on electric scooter video... but I don't know the configuration of the coils this motor has, is it star or delta? Please leave a replay if you know already, and guide how to determine? I have the same motor and I disassemble the rotor, just not unwind the stator, trying to figure out the delta/star to convert to 6 wires easily configurable as induction motors have. Thank you in advanced

@Reed-bu5kj 4 роки тому

The STM32 is powerful enough to just connect the BEMF to the ADC and make the calculations in software for the virtual zero and the zero cross, so you can skip the comparators. Use the DMA with interruptions when a conversion is finished to make it more efficiant. Good luck :D

@leschutesdelamordleschutes8583 Рік тому

hi, i see you know info on STM32 and esc ... I have a question it will sound weird, i want to make an ESC but at 400-600V ( yes 100S+ battery) i now is lots and with maybe 400-500Amps .. so wath do you phinks possible or not ?

@nanoindus 6 місяців тому

This is a very nice and detailed information. Very nicely done. I have one suggestion. When you explain the waveform, schematics etc, kindly keep the monitor zoomed and facing the camera. IN your can now, monitor is slant and very difficult to see what you are explaining. Yourself can be placed in corner in small places while you are explaining the schematic or any diagram etc. Very nicely done video. Full of information.

I have a doubt in 11:38 In BLDC, the rotor is attached with magnets. But in your diagram it shows that the coils are attached with it.It is nearly impossible to rotate the coils. I think it is a mistake or you just do it for explaination. However, Love You from India

Great video. Question. I'm replacing my ebike motor pcb. My original pcb has 5V GND SP H1 H2 and H3 components that's I'm familiar with and know how to connect. My replacement pcb has these connections PLUS a "K" (relay?) and "-" beside it. What is relay used for? Does K mean relay? And, since "K" is not a component on my original pcb does that mean this pcb will not work unless connected to some type relay? Tried looking online/Google. No luck. Need some hell.

Thanks for sharing your work with us - this is amazing! I'm just a little confused about what controls the total power supplied to the coils. I know the MOSFETs do the commutation, but are they further involved in this PWM too (switching on and off many more times in between the 6 steps)?

@cornishcat11 Рік тому

the power is controlled by the on time of the mosfets they only switch on once for each step

@theunis2958 Рік тому

@@cornishcat11 Is this on-time most effective in the beginning, middle or end of each step? Also, what limits me from switching on and off MOSFETs many times during a single step? I imagine I could make the motor turn really slowly without it getting stuck.

Thanks a lot! Please can you tell me about negative voltage more then -0.3V on input pin comparator, how to solve this problem?

@Reed-bu5kj 4 роки тому

The voltage will never go below 0V. When he is talking about negative voltage, he is acctually talking about the "virtual negativ voltage". What that means is that the voltage will be the below the "virtual zero" which will be your battery voltage divided by 2. You see, inside the motor you will have the current flowing through two coils and as Electronoobs is saying, we meassure the zero point between the two coils. Think of this as a regular voltage divider and perhaps you can understand what I mean :) Good luck.

You can surely transition to more powerful STM32F302, F303 controllers for Field Oriented Control, which is the gold standard in BLDC or PMSM motor control. ST supports the development using Motor Control Workbench and CubeMX. BluePill Boards cannot run FOC algorithm. Also IMS PCB and D2PAK MOSFETs can be used for the power stage.

My suggestion is to use a C2000 series Texas Instruments MCU as they are fast enough to be real time controllers. And the code for them compiles pretty close to that of the Arduino .
