As an example, look at a person riding a bicycle, with the person acting like the electric motor. If see your face tries to trip that bike up a steep hill in a gear that is made for low rpm, he or she will struggle as
they attempt to maintain their stability and achieve an rpm which will allow them to climb the hill. However, if they shift the bike’s gears into a swiftness that will create a higher rpm, the rider will have
a much easier period of it. A constant force could be applied with smooth rotation being offered. The same logic applies for commercial applications that 
require lower speeds while keeping necessary
torque.
• Inertia coordinating. Today’s servo motors are generating more torque relative to frame size. That’s because of dense copper windings, light-weight materials, and high-energy magnets.
This creates greater inertial mismatches between servo motors and the loads they want to move. Utilizing a gearhead to raised match the inertia of the motor to the inertia of the load allows for using a smaller electric motor and outcomes in a far more responsive system that is simpler to tune. Again, that is attained through the gearhead’s ratio, where the reflected inertia of the strain to the electric motor is decreased by 1/ratio2.
Recall that inertia may be the measure of an object’s level of resistance to improve in its motion and its own function of the object’s mass and shape. The greater an object’s inertia, the more torque is needed to accelerate or decelerate the object. This means that when the load inertia is much larger than the engine inertia, sometimes it could cause excessive overshoot or increase settling times. Both circumstances can decrease production collection throughput.
However, when the motor inertia is bigger than the strain inertia, the motor will need more power than is otherwise necessary for the particular application. This boosts costs since it requires paying more for a motor that’s larger than necessary, and because the increased power intake requires higher operating costs. The solution is by using a gearhead to complement the inertia of the motor to the inertia of the load.
