Using BTS7960 BTN8982TA PWM H Bridge motor controller module with Arduino library

Thanks! This detailed step-by-step walk-through on how to operate the BTS7960 motor driver was exactly what I needed

[@whitneydesignlabs8738]

Thank you so much! Works great. I moved your test code and wiring over to a Raspberry Pi Pico and it works great. All I had to do was ensure to use same GPIO pins as the code. It worked perfectly with no issues. BTW, I am using a wheelchair motor at 24vdc. So far under no load, running non stop for an hour, the chips don't even get hot.

[@prashkd7684]

Thanks for this wonderful analysis. I just bought one of these and you are absolutely right. The airgap between the driver and heatsink just doesn't allow it to get up to 30A. Thankfully my application only require 8 A max per motor so hopefully this driver will not get overloaded.

Thank you for liking. Sure I have. My videos have changed now checked them out kzbin.infovideos

[@rayleblanc7209]

Very good information. To improve the thermal conductivity, the heat sink can be removed from the 2 screws and modified a little to reinstall it on top of the IC chips with longer screws. Now the heat sink can do a proper job of absorbing the heat and prevent thermal shutdown. A fan can also be used for optimal cooling.

[@ericbommer2280]

Interesting idea, I have also seen comment of just adding thermal past. I just ordered 2 for a trolling motor project. I think I will need to run them in parallels. But after you comment I might try to add the other heat sink, and use them on both sides as an experiment.

[@willwalker2000]

@@ericbommer2280 I am also working on a trolling motor project and I've added thermal paste to mine, but I'm still not sure how well this is going to work

[@RichardHauser]

Yeah, I think they are M3 screws, so I got longer ones and flipped the heatsink over with some thermal paste on top. It certainly should work better.

[@sewingmachinesindetail]

I have just made a temperature check of one of these modules, and I think that the current specifications given are far too optimistic. The right steady state current should be about 7 Amps. I use at test set up with the H-bridge in a four quadrant configuration with a motor and 24 VDC. Both sides are driven by 10 kHz, so the motor see a 20 kHz PWM signal. I then measured the temperature on the surface of the packet and on the heat sink. With a current of 7 Amp to a loaded motor I get 124 degr. C on the surface and 84 degr. C on the heat sink. You may choose to set two modules in parallel in order to increase the current and power, that you can handle.

[@benfisher6085]

Great video - very thorough and informative. Lots of useful information in the comments, and love that you are so responsive to questions. My question (which I didn’t find in any of the comments) is whether the amount of heat generated in the BTS chips is related to the PWM frequency being used, and also whether maintaining 100% duty cycle will create less heat. I note in your video that your code continually increases then decreases the duty cycle during your test. Thanks, and keep up the great work!

[@robojax]

Hi, the datasheet we can see the maximum PWM frequency is 25kHz. I have not paid attention to the efficiency of module other than path resistance which is about 16mΩ. In the code the duty cycle changes but the frequency is fixed.

[@bobp5776]

Would u do another test on the power handling? Remove the heat sink and put it on top of the iC's . All you need are longer bolts . It fits beautiful. You may have to drill out the holes on the heat sink a tad to fit your longer bolts. I know its an old device. But i would bet there alot laying in junk boxes.

[@francoisguyot9770]

The heat sink could contact a soldermask free area connected with feedtroughs on that backplane of the board. It seems tha tthe footprint of that heatsink would fit on the component side without interfering with the other components tough. So i would try to switch its mounting and provide a small fan, mostly if the unit gets inclosed in a small water proof enclosure like it should if controlling an ebike or scooter.

Will your library work with a esp32? Can it work with stepper motors?

Thank you for great tutorials. Can the logic be powered by an external source instead of the arduino? And if so, would it be two wires to ground, one to the external power source and one to the arduino like you showed with the l298? I’m planning to use 3 bts7960 and a stepper motor driver in the same project but I’m concerned that it will be too many amps for the arduino. But maybe the enable pins and pwn would draw the same amps from the arduino even if I power the driver externally?

I opened the library and checked it there is nothing for current sensing. Sorry. if I see interest in this module a lot, I might try to make another video and show current sensing but as of now, it seems there is not enough people to encourage me to make new video on this. if someone pays me to write code and show how to measure the current and take action when current reached at certain value, I might consider working on it.

[@whitneydesignlabs8738]

@@robojax Totally understandable. Thanks for taking a look. I think the current sense function would be useful, but not not required to do the things I have in mind. The reason I asked about it, is that I have been experimenting with a with simplified code from Saravanan AL and wiring the R_EN and the L_EN together to a single GPIO, and not using the L_IS or R_IS pins at all. This means that it only takes 3 GPIO per BTS7960. I am working on a 6WD rover, so this means a single Raspberry Pi Pico, can run all six motor drivers and still have some GPIO left over. So I was wondering if those extra pin connections were necessary, in order to save GPIO pins on the microcontroller. Thank you so much for all your educating on KZbin.

The problem is that I don't understand how is possible that the connectros in this circuit can support 43A continiously. Everywhere in internet I read that this can work at this high current, but when I look to this small connector I think this can hardly resist it... I have some of this H-bridge and they work perfectly, but I never tried to use it at high current... Normally to can drive high current you need thick cable, but this thick cable doesn't fit in this small connectors...!! Another point: I have been reading in the side of this connector (marked in the green plastic) that this is designed for maximum 220VAC and 10A... So this is confirming a maximum current of 10A, isn't it?? I hope you can tell me something about it, probably you have more experience... Thank you so much in advance...! :-)

The datasheet shows that to select either the high-side or low side MOSFET transistors inside the BTN8982 will mean that when the PWM signal is high (+5 volt level) then the high-side MOSFET will be on therefore shunting the motor which will act a brake, which is not efficient? Any ideas?

[@ernievirata2551]

This is a great tutorial video.. well you always did. Thank you very much. BTw, I got one question, can I use this as a voltage regulator? maintain 70V and placed it on the high side of the load? Appreciate your reply thanks in advance.

[@robojax]

Hello, I have spent so much time to make those diagrams so there is not questions left. Here we have no HIGH or LOW. you connect your motor directly to this module. The maximum voltage is whatever I said in the video as I don't' remember it.

[@selaribrahimmosa5769]

im still confused .. how much its bear current cant this modul last 10 amper?????

[@AhmedHussainEng]

its fine and cheap and that is good, but 6 pins to the Arduino its so much , what if I want to use three motors?

[@robojax]

Yes Arduino mega which has over 50 pins

[@4SquareHI]

Will this module run on a D1 mini? I need Wi-Fi integration into Home Assistant Preferably with ESPHome or alternately MQTT. Thanks for the video

[@robojax]

Yes it will. I just Used digital pin

[@robvansuilen]

I ordered one of these units online. I think they are completely unsafe/dangerous. the BTS 7960 chips are together on the same cooling block without electrical insulation. Do you agree on the danger it poses? If so please put this in your video! because its putting people at risk!

[@robojax]

The module shown in video, the chips are on PCB and body of the chip is not attached to the heatsink. so it is safe. unless yours is different. see the module document robojax.com/learn/arduino/robojax_BTS7960_motor_driver_manual.pdf

[@robvansuilen]

@@robojax I think you misunderstood the point i was trying to make. I have a module that looks exactly like the one u use in your video. Your statement that the chips are not connected to the heatsink is not true (in my case)( and why else would they put on a heatsink in the first place??) . If you take off the heatsink you can see the problem yourselve. The design of the board is so that the chips must dissipate the heat from the chips trough the PCB by mean of Via's. These vias connect the back of the chips to the heatsink. In my case there is no silicon pad between the heatsink and the circuit board. Thus the only thing keeps the unit from short circuit is the thin black anodised layer on the heatsink. Your link in to the manual is not very useful im afraid. Please take a look at the following forum, it is in dutch, but the photo's are clearly showing the problem. www.circuitsonline.net/forum/view/152301

[@matthias417]

Just as a information also for the users here. If you switch off the debug mode, the library has a bug. if(this->_debug){ digitalWrite(pwm1Pin, LOW); ... This means, the pwn1Pin is only set to LOW, if you are in debug mode. So if you change direction (without debug-mode and without calling stop) both of the PWM will be bigger than 0, which you should avoid. Best regards, Matthias

[@robojax]

Hi, as I remember, the debug mode is not affecting other settings except printing something. What is the code you shown? is it from library?

[@matthias417]

@@robojax Looks like links are not allowed, i posted a link to the libraray. Yes, the Problem ist the library in RobojaxBTS7960.cpp in Line 84. Of cause the debug mode SHOULD only affect printing or sending to serial console, but in that line pwm1Pin is set to LOW only in debug mode. So the following code will trigger the bug: RobojaxBTS7960 motor = new RobojaxBTS7960(inhR, pwmPinR, isR, inhL, pwmPinL, isL, 0); motor.begin(); motor.rotate(100, 1); //motor.stop()

[@ockertgoosen5346]

Great video, i am trying to control 24V 15A motor using a BTS7960 module. it has burn out though...are you suggesting that it is because of the high current? it also started smoking after short operation.

[@robojax]

I am not sure why it smokes. Check the current. or may be install a fan to cool it.

[@mcliitkharagpur774]

whether 12V-40V10A DC Motor PWM Speed Control switch can be run directly through Arduino, or it require to run though BTS7960, Pls. Reply. Also, Pls. note, No Manual control switch is allowed for my work. My Motor Rating is: Rated Voltage: 24F/36V, current(F.L.): 5A, Speed: 5000 R.P.M. @180W (F.L.).

[@ranjan578]

U cannot run anything 40ma directly through Arduino, its just a microcontroller it should be used with motor drivers which can handle high current

[@markstephens7567]

Great information. Would it make sense to move the heat sink to the other side and clamp it down on top of the circuit components?

[@robojax]

right now the chips are not couching the heatsink. you can come up with other method to cool it down. yes.

[@angelleal3005]

How good is this H bridge in comparison to others such as l298 which is known to have some voltages drops across the drive itself.

[@robojax]

this is totally different. L298N can handle only 2A this is made for 30A and I've tested it but forgot how much it could handle. it is like you want to travel with small Toyota or large truck. if you don't need the truck then get small Toyota.

[@angelleal3005]

@@robojax Do you know how significant can the voltage drops be ? the L298 is known for having up to 5v drop when handling 2A. I wonder how big is the drop with this one. I really need a high efficient driver for my application.

[@bessybessy]

Fine! That is for one wheel control. Maybee you have code for two motors (like wheelchair ) for grassmover? I have Arduino Nano3, 9V switcher trafo and two BTS7960 motor driver, two used motors are on the way too. Thank You, M

Hey, great tutorial :), maybe i ask for to much, but could you help me to get the footprint or the library for proteus?

[@robojax]

Hey, Proteus is very expensive and they don't have free version for that reason I don't have it and don't like the software. Now they should offer free version even with limited capability.

[@eldarnoedobrea9022]

Thanks for the video. Do you think we can use 3.3 V logic from a raspberry pi for the PWM?

[@robojax]

yes you can use

[@christopherhughes6519]

Thanks!

[@robojax]

You are very welcome. Thank you.

[@MadDogPE]

Hi Robojax, nice video, very well explained ! I've been trying to learn and adapt your knowledge to my application, however I'm not really sure it'll work since I don't have any of this modules available at the moment. So hopefully you can help me with this question ... Do you think that connecting 02 BTS7960 modules in parallel will work to drive a 60A 24VDC motor ? PSU is a 24V 100A.

[@robojax]

Hi MadDogPE, Thank you. According to the datasheet www.robotpower.com/downloads/BTS7960_v1.1_2004-12-07.pdf on page 7 it says supply voltage max is 45V. So it will not work for your application.

[@MadDogPE]

Hi @@robojax ! thanks for the reply. Sorry but I don't understand your answer, I'm using 24V motors, that is less than 45V.

[@xchan1323]

hi Robojax, i have a big Motor RC car, L298N motor driver is not enough to drive the rear motors it gets really hot and it wont run when you put it on the ground, i bought a BTS7960. please teach me how to code and wire it to replace the old setup. thank you

[@robojax]

Hi Christian, If you watch this video and follow the instruction, you can control any DC motor. I've made it very simple using the library. Try watching the video without escaping.

[@ronniemoore773]

I have cleared the code and downloaded a fresh copy from your link. After installing, it keeps giving an error on the motor which was not declared

[@robojax]

when it says motor was not declared, then library is missing.

[@robojax]

just read the comments, 1000s of people used this. you must be doing something wrong. The code and downlead link has not been changed. so watch carefully. or post comment under someone else to see how they did it if you can't learn from my tutorial.

[@kartiknv5705]

Hey sir..excellent tutorial out there.I have a question that is..can only one motor be used with a single shield?or two?

[@robojax]

Hi, Perhaps you escaped the video. I have said in the video that you can control 1 motor. If you want to control 2 motor, you can but not fully. Details in the video.

[@ae20120]

Another great tutorial, thanks so much for your videos. I followed up the video but my motor doesn't run unless I remove the connection between BTS7960 Vcc&GND to Arduino Mega 5V and GND. It was working fine before with the Vcc and GND connected. Do you have any recommendations. Thanks so much.

[@robojax]

why have you connected the from VCC from this module to Arduino? I forgot what I did . if you follow the exact instruction, it should work. it has worked for 1000s other people.

[@juhaimebrahim2179]

Excellent video, however, I'm having issues downloading the BTS7960 library from the link in the description, please may you assist? @Robojax

[@robojax]

You are welcome. I just downloaded the library without any issue. it is your network or internet.

[@jismaelcr]

you can use this library with nodemcu esp8266, thanks in advance and greetings.

[@robojax]

Greetings, not it won’t work with ESP .
