DC Motor Driver LN298N: can it work as an ESC for robot motor control

Customer:

I’m interested in this product and I want to understand if a stepper motor controller is in some way an ESC (electronic speed control). Can I connect it to a receiver to control a motor on a robot? I don’t want to buy expensive ESCs from hobby shops because they’re overpriced and too powerful for what I need - I don’t need a lot of discharge current like 30-40A.

Pozdrav zanima me ovaj proizvod Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics dakle kontroler steper motora je na neki nacin ESC(electronic speed control)?? Zanima me dal mogu to spojit na jedan receiver kako bi kontrolirao motor na jednom robotu. Ne bih htio kupovat skupe ESC-ove sa hobbykinga jer su stvarno preskupi i prejaki za ono sto meni treba znaci bez puno kulona na izlazu (fast discharge) od npr 30-40A i te gluposti. Hvala unaprijed.

Soldered Support:

This is an H-bridge, actually a DC motor controller (for motors like the standard DC motors) that allows you to control the motor speed and direction. You cannot use it with stepper motors.

It is in a way an ESC, but an ESC can deliver much higher currents in a short time. An H-bridge cannot do this. This H-bridge can deliver a maximum of 4A. If that’s enough for you, you can use it.

ovo što ste poslali je H-bridge, zapravo kontroler istosmjernih motora(tipa: https://e-radionica.com/hr/istosmjerni-dc-motor.html) koji omogućuje kontrolu brzine vrtnje motora i smjera motora. Ne možete ga koristiti s stepper motorima.
To je na jedan način ESC, ali ESC može dati puno veće struje u kratkom vremenu. H-bridge to ne može. Ovaj H-bridge može dati max. 4A. Ako Vam je to dovoljno, možete ga koristiti :slight_smile:
