Specification — 800W

800W Brushless DC Motor — Power For E-Scooters, Light EVs And CNC Spindles.

800W is a sweet-spot specification for electric scooters, light EVs, CNC spindle drives and medium-duty industrial equipment. It provides substantially more torque than 500-600W motors while staying within a manageable current draw on 48V systems. Shenghe 800W BLDC motors are available in 86mm and 110mm frames with options for high-speed spindle or high-torque geared output.

  • 48V / 72V DC rated
  • 3000-4000 RPM base speed
  • 2.5 Nm continuous, 7+ Nm peak
  • 86mm and 110mm frames

Why 800W BLDC

Benefits Of An 800W Brushless DC Motor

  • High torque density — more power from the same 86mm frame as 500-600W motors
  • 90-93% efficiency keeps battery drain and heat low on EV platforms
  • Wide speed range supports both high-speed spindle and low-speed traction applications
  • Peak torque up to 3x rated for hill climbing and acceleration transients
  • Quiet operation under 55 dB for passenger EVs and indoor equipment
  • Regenerative braking capability extends EV battery range by 8-15%
