印度采购需求：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'm looking for high-torque, low-speed motors suitable for a 4-wheel drive AT Robot project. The motors need to provide reliable performance under varying load conditions and should be capable of handling the specific torque requirements for optimal operation. Please provide details on your available options, including specifications, pricing, and lead times. If you have any recommendations or alternatives that might suit this application, I'd love to hear them. Let's get this project rolling!
