## Notes

8115-frame BLDC (mini-Cheetah style) with 36:1 planetary reducer and built-in driver; 54 N.m high-ratio variant of the GIM8115 family (also sold as -6/-9). ~30 rpm output, 160W, 36-48V. kt 0.28 N.m/A is the MOTOR-side torque constant (before the gearbox). Rated (continuous) output torque is not separately published (54 N.m is the stall/peak figure). Only a gross shipping weight (~1.2 kg incl. packaging) is listed by resellers, not a net actuator mass, so weight\_g and torque\_density are left null and verified is false. 36:1 ratio makes it largely non-backdrivable.
