Mitigating Voltage Sag in High-Torque AMR Systems

A heavy-payload AMR project experiences severe voltage sag under peak torque, causing servo drives to throttle and resulting in emergency stops, thermal spikes, and velocity control issues. The system uses a 48V LiFePO4 battery pack and industrial-grade servo drives. Solutions must balance performance with payload-to-weight ratio and thermal management.
