I am working on a project where I need to control a stepper motor. Earlier I was using L298n motor driver. It worked fine until the stepper motor went into hold state. Because it draws maximum current and eventually burns the driver module.
Now I am upgrading my project to a new driver and I searched a lot and found tb6560 stepper motor driver (
controlador de motor paso a paso
) which is very good. Now I wonder if this problem will occur again with tb6560.
My stepper motor is nema17 stepper motor with 2.8 ohm resistance per coil and the current recommended in the datasheet is 1.4 amps, I don't know why they recommend about 12 volts/2.8 ohms = 4.3 amps per phase. Please guide me about tb6560.
Please reply me as soon as possible!

The TB6560 driver is a great choice for stepper motors, especially for motors like the NEMA17 you are using. One strength of the TB6560 is its ability to effectively regulate current, which helps to limit overload and protect the control module from being burned out by high current in the hold state.

Regarding the motor current calculation, you are correct in noticing that the voltage/resistance formula gives an unreasonable current value as you pointed out (12V/2.8Ω = 4.3A). However, in reality, NEMA17 stepper motors only need a small fraction of the maximum current in the hold state, so the TB6560 driver will automatically regulate the current supplied to the motor to avoid overcurrent and overheating.
The TB6560 driver usually has a function to reduce the current in the hold state (idle mode) to protect the motor and reduce wear. This should help solve the problem you are having with the L298N.
Good luck with your project and hope the TB6560 meets your needs!
