What is a Gear Reducer

A gear reducer, also known as a speed reducer and gearbox, is a power transmission device that reduces the input rotational speed. Reducers help increase the torque of the motor and allow a receiving device to rotate under the impact of the created torque. These devices improve the efficiency of operations. For example, motors are usually designed to run at a specific RPM. Although this speed can be adjusted by using a variable frequency drive, in many cases it is more advantageous to use a specific set of gears to adjust the speed.
