High Torque DC Geared Motor Outline Drawing
This motor includes a 30-pole magnet that rotates smoothly when powered. Changing the input polarity reverses the rotation direction immediately. Therefore, it provides silent operation for many project needs.
For example, engineers use this motor in smart home appliances, camera gimbals, robots, and balance cars.
