This brushed DC motor gear kit is perfect for students and hobbyists for their DIY kits. It is capable of running at 3VDC for better longevity of the motor at the cost of losing half the amount of speed and torque, compared to running it at 6VDC. That said, the mounted gears give a reduction ratio of 20:1 which means you will get about 20 times the amount of torque you would normally get from the motor itself.
