Specification — 48V BLDC Planetary Gear Motor

48V BLDC Planetary Gear Motor For Heavy-Duty Applications.

Heavy loads need high torque, and high torque at reasonable current means 48 volts. Shenghe 48V BLDC planetary gear motors combine high-power brushless rotors (100W–1500W) with multi-stage planetary gearboxes to deliver up to 350 Nm output torque in a compact coaxial package. Built for electric vehicle drive trains, industrial winches, heavy conveyors and powered material handling equipment where reliability under load is non-negotiable.

  • 100W – 1500W rated power at 48VDC
  • Multi-stage planetary, ratios 5:1 to 200:1
  • Output torque up to 350 Nm
  • Reinforced bearing option for belt/chain loads
Why 48V BLDC Planetary Gear Motors

Maximum Torque At Minimum Current Draw

  • 48V halves current vs. 24V — thinner cables, cooler connectors
  • Planetary gear distributes shock loads across multiple tooth meshes
  • 15–25% more efficient than equivalent worm gearbox at same ratio
  • Coaxial output fits inline with driven shafts — no offset adapters
  • 90–93% motor efficiency combined with 85–97% gearbox efficiency
  • Brushless longevity and low maintenance for continuous industrial duty
