Specification — 300W

300W Brushless DC Motor For Pumps, Conveyors And Small Electric Vehicles.

300W is the entry point for serious industrial and mobility drives. It provides enough power for water pumps, packaging conveyors, automatic guided vehicles and light electric scooters while fitting within a 60mm or 80mm motor frame. A 300W BLDC motor on a 48V bus draws just 7A at rated load, keeping wiring simple and controllers affordable. Shenghe manufactures 300W brushless DC motors with planetary, worm and spur gear options for high-torque output.

  • 24V and 48V winding options
  • 60mm and 80mm stator frames
  • Planetary, worm and spur gearbox options
  • Continuous-duty rated for industrial applications
Why 300W BLDC

Benefits Of The 300W Power Class

  • Enough torque for conveyors, pumps and light traction without oversizing
  • Moderate current draw — 7A at 48V, 13A at 24V — uses standard connectors
  • 60mm/80mm frame fits NEMA 23/34 mounting patterns
  • 88-92% efficiency reduces heat buildup in enclosed equipment
  • Gear motor output torque up to 40 Nm with planetary reduction
  • Available in both continuous-duty (S1) and intermittent-duty (S2/S3) ratings
