Where to buy H-bridge for my project!

Good afternoon my friends!
I have a big problem finding an H bridge that meets my needs to do my project.
Any participant indicate where to buy these H bridges?
I need a bridge H 24V 120A.

Using as a half bridge the drivers offer already 60A. If you connect two together you get 120A.

Usando como uma meia ponte os controladores já oferecem 60A. Se você conectar dois juntos você começa 120A.

thanks for the answer!I have to buy two plates of this for each engine?

I found this H bridge in china market will be serving?
with SMC3 more Arduino?

yes

Good day!
I could be using this for my 2Dof plara?
BEST H BRIDGE DRIVER FREE MARKET, TESTED AND APPROVED !!
DRIVER BRIDGE HIGH PERFORMANCE H P / ENGINES TO 43 AMPS
TRANSISTOR CONTROL CAPABLE OF CONTINUOUSLY 110A, BUT established
THE POWER REMAINS IN 60A
PEAKS OF CURRENT 110A
VOLTAGE / CURRENT 12V The 24V - 60A
CONTROL VIA PWM
(1/0) - LEFT
(0/1) - RIGHT
(1/1) - BRAKE
(0/0) - STANDBY

@Claudemir that sounds interesting how about the cost? BTW a very big bridge... and obviously hand made.

My doubt is the pinouts!
Can I use this card with the Arduino more SMC3?
Utiliso the SMC3 code currently.
I was using the ponteH Chinese BTS7970, but I'm struggling to buy and send to Brazil.
Then I found the card in Brazil.
How do I turn the board pinouts with Arduino?

Currently my electric scheme is this!




But put this new card has 3 pins PWM1 PWM2 and GND!
I'm confused!
Could help me?

Please ask the vendor for a data sheet if available.

Thank you for your quick reply Pit !

I spoke with the seller, and it does not have a document of this board.
He only said: You board has three pin PWM 1 PWM 2 and GND.
And this was progetada for X-YES!
Should I use a different code to put this board?

Probably @RufusDufus, @RacingMat or @prilad can say more - if only PWM is enough to drive a motor. IMO you can only control the speed by a potentiometer and nothing else (like fast, slow but no motion control). I am not the electronic guru, so take this with care

Hello! @RufusDufus,Pit
I found this board.
It can be used in my project?
So see it supports normal for each motor 100A and 200A peak.
I am sure that a card will only work well for two DC motors 23A?

1 Use smt, high integration, superior layout design, very beautiful, small size,
Built-in two high-powered drive the dc motor channels, only 82 mm size drive module * 70 mm;
2, large heat sink on the large current can be effective for heat drive module, keep good stable performance;
3, the Maximum current module 100a, and the resistance only 0.0015 ohms;
4, switching frequency is high, the most affordable 60 kHz, effectively to debug engine;
5, control interface is very simple: A1, A2 = 0.0 to brake; A1, A2 = 1,0 forward; A1, A2 = 0.1 to reverse;
Pa wave input for PWM (Motor Speed Regulation); G for common ground (Channel B for the same control);
6, all MCU of 3.3 V and 5 V are can control this module, and only need a motor supply channel (12 V ~ 48 V);
Unit Module mechanical parameters:
1) Size: 80 mm * 70 mm * 25 mm;
2) positioning hole: Diameter = 3 mm, 4 Holes distribution, the spacing of 74 mm * 62 mm;
3) Packing antistatic bag.
This module is super large motor drive voltage (highest theory can reach 60 V) General may reach 48 V, using high quality MOS power thus Max. Current may be up to 100A. This module can be used for general DC motor drive high power, stable performance thus very suitable for robot competition, a race car, Freescale competition, etc.

I have seen this bridge already here on xsimulator. net, dunno which chip is doing the job on it . If you can buy the bridge on good terms why not. But beware the bridge has not been approved yet (as far as I know), so do not complain if your experiments are going wrong

Have you a link to that board @Claudemir ? Id be amazed if it can cope with that much current.

The cooler makes me suspicious about the current rates...but why not to order a test unit and try to blow it

WOW at that price its an expensive fire cracker !!

@SilentChill after all the constant coming and going of "cheap h-bridges" I am given to the sabertooth's if strong bridges are needed (excluding the MMs if not DOA)

Thank you guys for being helping me!
Pit, SilentChill,
my doubt is can I connect the two engines in one card?
Or do you have to have two?
If this board can control two motors, so I can turn on a plate for each motor by increasing the amperage capacity, am I right?

you could probably use it as one motor driver using just the inputs from pwm1 and then another for just pwm2 and so on. I dont know 100% if it will work or not as they are untested here.
