How Do Planetary Gears Increase Torque?

How Do Planetary Gears Increase Torque? A planetary gearhead takes a high-speed, low-torque input, say from an electric motor, then increases torque and reduces speed at the output by the gearhead ratio. This lets motors run at higher, more-efficient rpms in equipment that operates at low speeds. Are planetary gears Backdrivable? A: Yes, Micron planetary

Gearing On A Multi Speed Bicycle What Is The Advantage Of A Large Pedal Sprocket?

Gearing On A Multi Speed Bicycle What Is The Advantage Of A Large Pedal Sprocket? You can gear up by using a smaller rear sprocket or a larger countershaft/front sprocket. Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front
