Specification — 5000W High-Power

5000W Brushless DC Motor For Electric Vehicles, Marine Propulsion And Heavy Industrial Drives.

5kW represents the upper range of standard BLDC motor production, where thermal management, controller sizing and battery architecture become critical design decisions. At this power level, brushless technology delivers a decisive advantage over brushed motors in efficiency, service life and controllability. Shenghe produces 5000W BLDC motors in 72V and 96V windings with planetary gear options for torque-dense drivetrain integration.

  • Rated power 5000W continuous
  • 72V / 96V DC voltage options
  • Planetary gearbox with ratios 3:1 – 30:1
  • Fan-cooled or liquid-cooled configurations

Why 5kW BLDC

Benefits Of The 5000W Power Class

  • Drives electric vehicles up to 800 kg gross weight on flat terrain at 30–40 km/h
  • Marine-grade versions propel boats up to 8 m at displacement speed
  • Peak output up to 10kW handles steep grades and rapid acceleration
  • 96V winding reduces current draw below 60A — compatible with standard EV contactors
  • Brushless design eliminates brush wear — critical in continuous-duty industrial service
  • FOC-compatible for smooth, quiet operation across the full speed range
