High Torque Motor 218.4:1

DC Brush Gearmotor, 218.4:1 ratio, 500 oz-in continuous torque

The 218.4:1 Gear ratio provides maximum torque at minimal current draw. Observed performance: 2 inches/sec. at 12 volts/ Max continuous tractive force is 7.5 lbs @ 0.5 amperes per wheel.This motor is particularly well suited to off road use where short distances and precise motion is required. Due to the low current draw and extended run time, applications might include emergency/disaster reconnaissance and/or biological field observations over very limited distances.
