gear reduction

Speed-to-force conversion

Gear reduction is a mechanism that uses gears of different sizes to decrease rotational speed while increasing torque.

A small gear driving a larger one slows the output but multiplies turning force—essential in applications from car transmissions to power tools.

The gear reduction lets the motor spin fast while the wheels turn slowly with more power.
