DC Motors

DC Metal Gearmotors are the most powerful and largest you will find on our site. Coming in at a whopping 37mm (1.46") in diameter, they are available in a variety of gear ratios from 6.3:1 to 150:1 at 12V. Composed mostly of spur gears, however, the first stage features helical gears for improved efficiency and reduced noise. These motors will run at voltages above and below the rated voltage; lower voltages might not be practical in your project, and higher voltages could start reducing the lifespan of the motor.
