Hi guys!
I'm trying to drive my stepper motor NEMA17 model# 17HS1538 using L298N. It needs 1.65A per phase.
My motor doesn't rotate, it just vibrate and the driver gets very hot.
Everything is hooked up properly as per instruction to use L298N with bipolar stepper motor.
Can anyone help me please?
The motor is 17HS1538, it's data sheet is available on searching in Google, it's written 1.65A per though.
No, not without more information.
Please post a wiring diagram.
L298 is a really crappy motor driver by today's standards and even worse stepper driver. It will not handle the 1.6A coil current of your stepper. The best thing to do with the L298 is to take it out your front door and throw it as far as you can. Then go back inside and order a stepper driver appropriate for the stepper. A DRV8825 would be a good choice. Make sure that you follow the instructions on setting coil current. It is an absolutely necessary step.
You will need a power supply of at least 8V for the DRV8825. 12V and up to the limit of the driver will be better.
You should make helping you as easy as possible. Making us search for a data sheet is not making it easy.
Thank you very much. I'm ordering A4988.
Is it better than DRV...?
DRV8825 can work with 2A without attaching additional cooler, A4988 only with cooler.
compare datasheets from both.
I recommended the DRV8825 because it can handle 1.5A without a heat sink. A4988 will need a heat sink and forced air cooling at 1.5A.
This comparison of the 2 may be of interest..
On both boards, setting current limit is necessary. Be aware that the current sense resistors on the A4988 are not all the same. One must confirm the values of the resistors on your modules so that a correct value can be used in the formula to calculate the proper Vref to set.
Hi,
What are you using for a power supply?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks.. Tom...
