It is not better to have a single PWM signal and the ENABLE signals of the directions of rotation, to have them through an inverter. In this way they will NEVER be both enabled and a Single PWM signal would serve to rotate the motor in both directions. Let's imagine a 2 motor application, we would need 4 PWM signals in this way and only 2 if we do it as I propose. Does it seem correct?
Hi! I'm confuse why do you set L_IS and R_IS as OUTPUTs, they should be set as INPUTs. Pin IS of the BTS7920 is an OUTPUT Pin !?! Also, I have made a schematic and L_IS and R_IS are directly connected to the respective pin 5 of the BTS7960 while all OUTPUTS to the BTS7960 such L_PWM, R_PWM L_EN and R_EN goes through the buffer 244 before interfacing to BTS7960 motor driver.
The two boards are effectively two different DC powered subsystems. The Arduino is powered from the USB lead and the motor driver from (in this implementation) a 9V DC battery. In order for two such subsystems to signal to one another they must have a common ground reference (i.e. to agree on what 0 Volts looks like!) thus the need to cross connect their ground leads - but just once. Multiple common ground connections between two subsystems can cause problems. Without that common ground connection, they wont communicate properly or at all, and also they may damage one another.
The Arduino numbers on your diagram don't seem to match those in the code. The pins used in the code start from 2 but on the diagram they start from 1. As has already been said R_IS and L_IS should be set as INPUT and not OUTPUT

Sean Lyon 4小时前 Great video! I am making a ball launching machine using a 12V 30W motor and a 16.8 Ah Lithium battery. I need the motor to spin one second and wait for 5 seconds and repeat this cycle. Would this motor controller work with this setup? Thanks

Hello, how do i use the low-side MOSFET inside the BTN8982 when the load (Motor) is connected to the Vs + supply (+24 Volts) and O/P terminal (tab and pin 4)? I'm using a PWM drive signal at the input of IN while INH is held high (logic +5volts)? 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?
Nice one friend! I use the IBT-2 and arduino on my DIY motion simulator (full frame platform) which interfaces with Racing simulator software games! You did a good job on this post! DMAX motion simulator ch
You can simply connect two motors to the motor output pins and they will work together. But if you want to control each of them individually, then two BTS7960 is needed.
@@IngenieroLab I want to control two motors and each of them individually and I think I will use two BTS7960s. However, Are there enough pins for Arduino to connect two BTS? And as I see in your video, pin R_IS and L_IS you set LOW logic the whole time. Is it okay if I don't connect these two pins to Arduino? Hope u answer me this question. Thank you.
Dear, I have one question about this H-bridge. I really appreciate if you could help me, answering to this comment. The thing is that I need to use this H-Bridge for a project I'm developing to can control something at 40A continiously. 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...! :-)
It can not handle 43A continuous. It can only handle about 10-15A. The problem is that the heatsink is mounted in a stupid way, it should be mounted directly on top of the two main driver chips, using a good thermal paste. This will help it handle more, but how much exactly I do not know. The 43A rating is that of the chip datasheet, which assumes "sufficient" cooling. If you want to guarantee 43A, you should mount a very good heatsink.
@@ChielScape I have three of these, with a 120mm intake fan blowing on the fins and a 90mm exhaust fan. I've been running them for over 300 hours and the most current my motion sim rig has shown is 36 amps (12vdc) and that's at big directional change acceleration to hard braking. My motors are 50:1 and are pretty big. But I agree with you that the heatsinks should probably be ON the Chip.. DMAX motion sim channel
Hello. What will happen when you apply a PWM signal to RWPM and LPWM at the same time? Will it stop or will there be a short circuit and damage? Witaj. Co się stanie gdy podasz sygnał PWM do RWPM i LPWM jednocześnie ? Zatrzyma się czy będzie zwarcie i się uszkodzi ?
Yeah you can control two motors with with joystick using bts7960. Recently I will provide a video explaining that to everyone. Thanks for your response.
Only if you plan to control those motors together. It cant separately control 4 motors, only 1 with its 2 terminals: 1 positive, 1 negative (they change polarity to reverse direction) for the motor output. Otherwise you would clearly see 8 motor output terminals. Still, if the total current consumption of those motors isnt way too high, you could connect all 4 motors to the same 2 terminals. I guess you want to control the motors independently, so this module isnt for your application.
@@IngenieroLab How so? There are only 2 high voltage/current outputs and for a stepper motor you need 4 ideally or at least 3. If you know how, please let me know, that would help a ton. As I'm trying to drive a number of steppers and I'm in search for simple and cheap drivers.
It depends on the wiper motor. If it has just two connections into the motor then it may work - but that will depend on the current drawn by the motor (i.e. what amps it consumes). There should be some kind of label on the motor that says (for example) something like "12V 15A" meaning it needs 12 Volts at up to 15 Amps. This board supposedly can supply up to 42 Amps - but a guy called RoboxJax did a detailed test of this board here on TH-cam and concluded that 15 Amps is probably a safe continuous current limit for this board - else it will overheat. Having said all that, the board does feature over-amps shutdown protection so there would be little to lose by trying out your 2-wire motor to see if it works - assuming your power source (car battery?) is also up to the job.
@@alanmusicman3385 I would suggest download the PCB mount with 40mm fan and add active cooling on there if someone plans to run at the higher range of the limits so that it can prolong the life

Great one! Simple one for beginners. You haven't given the unnecessary things which will help someone to start their journey....
In the sketch pins are wrong defined. The correct pin definitions are: R_IS = 1; R_EN = 2; R_PWM = 3; L_IS = 4; L_EN = 5; L_PWM = 6;
the pins are wrong defined in the example sketch...

You're right. X_IS pins are actually outputs from the motor driver. The TH-camr has no clue.
Could you explain why you need to put both motor and battery ground together ?
To complete the circuit...
The two boards are effectively two different DC powered subsystems. The Arduino is powered from the USB lead and the motor driver from (in this implementation) a 9V DC battery.
In order for two such subsystems to signal to one another they must have a common ground reference (i.e. to agree on what 0 Volts looks like!) thus the need to cross connect their ground leads - but just once. Multiple common ground connections between two subsystems can cause problems. Without that common ground connection, they wont communicate properly or at all, and also they may damage one another.
Do you need to wire up 3,4,5,6 if you are only intending to use PWM? (pins 3,6 on Arduino?) I don't understand what IS and EN stands for.
Thanks
