Small 12 Volt Worm Gear Motor Specification Sheet

What is worm geared motor?

DC worm gear motor consists of a screw-like worm and a gear wheel, used for reducing speed and increasing torque in a compact space. Its design allows easy turning of the gear by the worm, while often preventing reverse motion, a feature known as self-locking. Commonly they’re valued for high torque, compactness, and preventing backdrive.

  1. Michael Moebius

    This 24v metal gearmotor is a really smart design. It is high torque, 70Kg.cm was strong enough for project. Used this on a retractable antenna for company’s RV, works well in this application. As a purchaser, this is the first smooth and pleasant experience 🙂
