Specification — 72V 2000W

72V 2000W Brushless DC Motor For High-Performance EVs, Marine Propulsion And Heavy Machinery.

2000W at 72V is where electric drive starts to compete with small combustion engines. The motor delivers enough sustained power to propel a loaded cargo vehicle at road speed, push a mid-size boat against current and run heavy-duty industrial equipment through full shifts. At 28A rated current, the electrical system remains manageable — no exotic cabling or oversized contactors required. Shenghe manufactures 72V 2000W BLDC motors in 110mm and 130mm stator frames with high-torque planetary and worm gearbox integration.

  • Rated voltage 72V DC (60V–84V operating range)
  • 2000W continuous rated power, 3500W peak
  • Planetary and worm gearbox options
  • Hall sensor standard, 1000-line encoder optional

Why 72V 2000W

Benefits Of The 72V 2000W Power Class

  • 2000W continuous with 3500W peak — handles acceleration, hills and wave resistance
  • 28A rated current keeps wiring, connectors and controller costs reasonable
  • Competes with 2–3 HP combustion engines in many EV and marine applications
  • 110–130mm frame delivers high torque density without excessive size or weight
  • Class H insulation option for extreme thermal environments
  • Field weakening extends speed range above base RPM for highway-capable EVs

Common Applications For 72V 2000W BLDC Motors

  • High-performance EVs: Four-seat enclosed NEVs, electric cargo vans and last-mile delivery vehicles up to 50 km/h
  • Marine propulsion: Sailboat auxiliary drives, fishing boats and pontoon boats in the 4–6m range at 7–10 knots
  • Heavy industrial machinery: Concrete mixers, grain augers, wood chippers and other equipment replacing small diesel engines
  • Mining and tunneling: Ventilation fan drives and material transport vehicles in underground mines where zero emissions are required
  • Agricultural machinery: Electric sprayer pumps, feed processing equipment and greenhouse ventilation systems
  • Construction equipment: Electric plate compactors, small concrete vibrators and portable hoist motors

Technical Details For Integration

  • Battery sizing: 20S Li-ion 40Ah or 24S LiFePO4 50Ah for 1-hour runtime at rated power
  • Controller requirements: 72V/50A FOC controller with field weakening; CAN bus for vehicle integration, analog for standalone
  • Thermal management: Class F standard, Class H (180 °C) optional; forced-air or liquid cooling for continuous heavy-duty use
  • Mounting: IEC B5/B14 flange, foot mount with vibration dampers; marine transom plate for boat installations
  • Shaft options: 22mm keyed standard; hollow shaft, splined and marine propeller taper available
  • Operating temperature: -20 °C to +50 °C ambient; Class H insulation extends to +65 °C with derating
