巴西采购需求：步进电机、电机轮、步进驱动器、机器人轮、机器人电机、AMR 直流电机

I recently purchased some motors from your company, and unfortunately, I encountered an issue with one of them. I accidentally shorted the hall sensors, which has affected their functionality. I'm reaching out to inquire whether it's possible to replace the damaged hall sensors. I'm keen to know if you offer such replacement options for the sensors. Additionally, could you please provide the part number for the sensor IC used in these motors? This information would be greatly helpful for both sourcing the right components and ensuring compatibility with the existing setup. Looking forward to your prompt response on this matter. Thank you!
