48V DC Gear Motor — Brushed & Brushless For AGV, Electric Vehicle & Heavy Automation
48V is where DC gear motors meet serious torque. At this voltage class, DC gear motors power AGV traction drives hauling 1,000+ kg loads, electric vehicles climbing grades, and heavy conveyor lines running 24/7. Shenghe manufactures both brushless (BLDC) and brushed DC gear motors at 48V from 100W to 2000W, paired with planetary gearboxes for traction and worm gearboxes for self-locking applications. BLDC is strongly recommended at 48V — the efficiency advantage directly extends battery runtime in mobile applications. For selection guidance, see our DC gear motor selection guide.
Brushed vs Brushless at 48V
Why BLDC Is Strongly Recommended at 48V
At 48V power levels, the efficiency gap between brushed and brushless matters more — every percentage point translates to longer battery life, less heat, and lower operating cost.
At 48V, brushless is the default. Choose brushed only for intermittent-duty, cost-driven applications where total operating hours stay under 1,000/year. For the full comparison, see our brushed vs BLDC comparison.
Where 48V DC Gear Motors Are Used
- AGV traction drives — 200W–1500W planetary gearbox, powering automated guided vehicles hauling 500–3000 kg loads in warehouses and factories
- Electric tuggers & tow tractors — 500W–2000W planetary gearbox, pulling trailer trains of 2,000–10,000 kg in manufacturing and logistics
- Electric vehicles — e-rickshaws, golf carts, utility vehicles; 500W–2000W with planetary gearbox for efficient traction
- Heavy conveyor systems — 200W–1000W with spur/helical or right-angle gearbox for continuous 24/7 material transport
- Electric pallet jacks & forklifts — 400W–1500W planetary gearbox for traction and hydraulic pump drives
- Industrial machinery — packaging lines, CNC auxiliary, textile machines; 100W–800W with application-matched gearbox
- Winch & hoist — 200W–1000W worm gearbox for self-locking under load (brushed acceptable for intermittent duty)
