As an example, consider a person riding a bicycle, with the individual acting like the motor. If see your face tries to ride that bike up a steep hill in a gear that is created for low rpm, she or he will struggle as
they attempt to maintain their stability and achieve an rpm that may permit them to climb the hill. However, if indeed they change the bike’s gears into a velocity that will create a higher rpm, the rider could have
a much easier period of it. A continuous force can be applied with easy rotation being supplied. The same logic applies for commercial applications that want lower speeds while preserving necessary
torque.

• Inertia matching. Today’s servo motors are generating more torque in accordance with 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. Using a gearhead to raised match the inertia of the motor to the inertia of the strain allows for using a smaller engine and results in a more responsive system that is easier to tune. Again, this is attained through the gearhead’s ratio, where the servo gearbox 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 change 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 thing. This means that when the strain inertia is much bigger than the electric motor inertia, sometimes it can cause excessive overshoot or enhance settling times. Both conditions can decrease production collection throughput.

However, when the engine inertia is larger than the load inertia, the engine will require more power than is otherwise necessary for the particular application. This increases costs since it requires paying more for a motor that’s larger than necessary, and because the increased power usage requires higher operating costs. The solution is by using a gearhead to match the inertia of the electric motor to the inertia of the strain.
