100:1 Micro Metal Gearmotor HP with Extended Motor Shaft


SKU: ROB-074


This high power (HP) 100:1 gearmotor is a miniature brushed DC motor with a 100.37:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These gearmotors have a 0.365″-long, 3 mm-diameter D-shaped output shaft on one end and a 4.5 x 1 mm extended motor shaft on the opposite end – perfect for rotary encoders!

The output shaft spins at around 320RPM at 6V and produces 30 oz-in (5.0 kg-cm) of torque. Current draw is 120mA when free running and 1.6A at stall.


  • 6 V: 320 RPM
  • 30 oz-in / 1.6 A stall
  • 120 mA free-run
  • 100.37:1 Ratio
