Brushless DC Gearmotor / BLDC Gear Motor

Spur and Planetary Brushless Motor Gearbox

GEMS provide both planetary and spur type of brushless motor gearboxes with gear ratio ranging from 1:3 to 1:720. Planetary gearheads share the load through a pinion over multiple mating gears. They generally have higher torque to size ratio, higher efficiency, lower backlash and longer lifespan than spur gearheads. Brushless dc motors integrated with the gearbox are perfect solutions for motion control applications where high accuracy, maximum efficiency and a small package are required. Our brushless dc gear motors are available in NEMA 17 NEMA 23 NEMA 34 NEMA 42 frame size. Various custom options are also available as below for your specific needs.  For low speed positioning application, please take a look at our geared stepper motor products.

  • Dual shaft with the installation of encoders or brakes
  • Different bearing and lubricant options for extreme temperature operations.
  • Custom connectors, cable harnesses and shaft modifications
