Presentation functional version 2DOF arduino and IBT2h

De boas ?
Apresentando nossa versão agora funcional do SMC3 Arduino:

Cool ?
Introducing our now functional version of the SMC3 Arduino

UPDATE:
A very important tip is to put thermal paste on the ibt2 bridges

This photo is just to illustrate, because this bridge is burned, put enough thermical paste to cover this little holes

Muito legal Luis Arnaldo, uma pergunta, eses motores cual sao ?

Very cool Luis Arnaldo, a question, are these engines what are they?

Hey there! is a GBP 24v BOSCH

Are you sure that's the engine reference, because I only get Ford mondeo engines at 12v.

I would appreciate it if you can send a more specific link.

Thank you.

MOTOR DE ARREFECIMENTO 24v 350W

I used IBT2s, but they immediately burned, they don't have a good logic to control PWM signals

yes, the code SMC3 v1.0. two second the hbridge burn....

You apparently connected them incorrectly, they were bad to start with, or you didn't change SMC3 mode to IBT-2 first (assuming you are using them within their stated specs).

But with IBT2 is it possible to power motors with 15 amps 12v?

Yes. Specs say up to 27v and 43a but I wouldn't recommend pushing them to the limits.

I had done the test to feed them at 24V and burned. I did read the datasheet btn7960 to an electronic technician, and he told me that the maximum "allowed" voltage to obtain current performance is 18 volts.

Product description
Instruction:
This driver uses Infineon chips BTS7960 composed of high-power drive full H-bridge driver module with thermal over-current protection. Double BTS7960 H-bridge driver circuit, with a strong drive and braking, effectively isolating the microcontroller and motor driver! High-current 43A.

Electrical performance:
Model: IBT-2
Input voltage: 6V-27V
Maximum current: 43A
Input level: 3.3-5V
Control method: PWM or level
Duty cycle: 0-100%
Input port:
1.RPWM: forward level or PWM signal input, active high
2.LPWM: Reverse level or PWM signal input, active high
3.R_EN: forward drive enable input, high-level enable, low level off
4.L_EN: Reverse drive enable input, high-level enable, low level off
5.R_IS: forward drive current alarm output
6.L_IS: Reverse drive current alarm output
7.VCC: +5 V power output, 5V power supply connection with the microcontroller
8.GND: signal commo

No, nominals are 18 volts.
Up to 28 volts, but out of range (deviation possible)

What does that prove? 27v is within the 28v extended range. Also the Ibt2 uses more components than just a single bts7960 chip. I admit that its not unusual for the Chinese to exaggerate things but you asked if it would work at 12v and 15a which is well within specs, even your own. I think you just f&^ked up somewhere. Good luck I'm out!

First check voltage! 28v max @motiondynamics and thermal attention

I would check first if the arduino firmware was correctly configured x ibt2.
second check pwm connections between arduino pins and ibt2 are exact.
power supply without load for test or with a fictitious load resistance of 15-20 ohm 10w and to measure voltage or wave form in output.
if everything is ok, connect the motor.
ibt2 are in my opinion difficult to roast. not even with a motor with brushes short on mine and dead, he just moaned.
for continuous use I recommend forced ventilation

Through my test, the parameters that IBT2 can continue to work are: voltage 12v and current 10a. The so-called maximum current of 43a is only the instantaneous maximum value that IBT2 can withstand.

I can confirm that for years I have been using 2 43 A ibt in parallel powered at 12.2v 66A. the only one that is affected by the effort is the poor power supply that when it reaches the maximum current begins to drop in voltage. (this regarding the steering wheel DC motor)

The IBT2 have been removed from its heatsink, replaced the original (very ugly) cross screws with Allen screws, spread thermal paste and tightened the heatsink well.
I got everything inside an ATX case and used the 12cm fan to keep everything cool.
never burned a component,
I suppose that by increasing the tension beyond 15-18v they would start to suffer,
good things Marco
PS: the steering wheel in long curves or during race use, remains at strong currents for a long time, the only things that heat up a lot are the cables and the engine.
