Specification — 48V 400W

48V 400W Brushless DC Motor For AGVs, Electric Scooters And Mid-Range Industrial Drives.

The 48V 400W specification occupies the sweet spot between lightweight portability and serious industrial capability. At only 10A rated current it keeps the power electronics compact and the cabling light, while delivering enough torque to propel AGVs through loaded warehouse aisles, push electric scooters up moderate grades and drive mid-speed conveyor lines in manufacturing. The 48V bus aligns with the growing ecosystem of EV and energy-storage batteries, making sourcing straightforward and cost-effective.

  • Rated voltage 48V DC (36V–58V operating range)
  • 400W continuous rated power
  • 80mm frame diameter
  • Hall sensor standard, 1000-line encoder optional

Why 48V 400W

Benefits Of The 48V 400W Power Class

  • 10A rated current — half that of 24V at equal power, simplifying controller and wiring
  • Directly powered by standard 13S/14S lithium EV battery modules
  • Enough torque for differential AGV drives handling 300–500 kg payloads
  • Peak power headroom to 600W for short acceleration bursts
  • Regenerative braking recovers kinetic energy during vehicle deceleration
  • Still below 60V DC SELV threshold — no special high-voltage precautions required

Common Applications For 48V 400W BLDC Motors

  • AGV traction: Differential wheel drive for 300–500 kg payload automated guided vehicles in warehouses and factories
  • Electric scooters: Rear-wheel hub or chain drive for urban commuter scooters rated 25–30 km/h
  • Mid-range conveyors: Belt and chain conveyors moving 50–100 kg packages at 0.5–1.5 m/s in logistics centres
  • Commercial cleaning: Ride-on floor scrubber brush drives and squeegee vacuum motors
  • Industrial fans: Variable-speed centrifugal blowers for dust collection, drying tunnels and process ventilation
  • Golf carts and utility vehicles: Auxiliary pump, fan and steering-assist drives on 48V platforms

Technical Details For Integration

  • Battery: 13S Li-ion (48.1V nom) or 16S LiFePO4 (51.2V nom), 20–40Ah for AGV use
  • Controller: 48V 15A FOC driver recommended; supports speed, torque and position modes
  • Thermal class: Class F (155°C) insulation for sustained high-load duty cycles
  • Mounting: B14 flange (4x M5) or custom wheel-hub adapter for AGV integration
  • Shaft: 14mm keyed standard, hollow-shaft option for through-bolt wheel mounting
  • Braking: Optional 48V electromagnetic brake (3 Nm) for parking and emergency stop
