As an example, look at a person riding a bicycle, with the individual acting like the engine. If that person tries to ride that bike up a steep hill in a gear that’s created for low rpm, he or she will struggle as
they attempt to servo gearbox maintain their balance and achieve an rpm that may allow them to climb the hill. However, if they shift the bike’s gears right into a rate that will produce a higher rpm, the rider will have
a much easier time of it. A continuous force can be applied with even rotation being offered. The same logic applies for commercial applications that want lower speeds while keeping necessary
torque.

• Inertia coordinating. Today’s servo motors are producing more torque relative to frame size. That’s because of dense copper windings, lightweight materials, and high-energy magnets.
This creates greater inertial mismatches between servo motors and the loads they want to move. Utilizing a gearhead to better match the inertia of the motor to the inertia of the strain allows for using a smaller motor and results in a more responsive system that’s easier to tune. Again, this is achieved 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 way of measuring an object’s level of resistance to improve in its motion and its own function of the object’s mass and form. The greater an object’s inertia, the more torque is required 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 conditions can decrease production range throughput.

However, when the motor inertia is larger than the strain inertia, the electric motor will need more power than is otherwise essential for this application. This increases costs since it requires spending more for a motor that’s bigger than necessary, and because the increased power intake requires higher working costs. The solution is to use a gearhead to complement the inertia of the motor to the inertia of the load.
