Lynxmotion - Spur Gear Motors

Lynxmotion Wheel Calculator
A Javascript-powered calculator to find the wheel speed, motor RPM, or wheel diameter.

These motors are neutrally balanced, meaning they are designed to spin at the same RPM in either direction.

The torques listed are calculated by the manufacturer. Lynxmotion does not guarantee the suitability of these motors for any application.
