As an example, consider a person riding a bicycle, with the person acting like the engine. If see your face tries to trip 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 will permit them to climb the hill. However, if they change the bike’s gears into a velocity that will produce a higher rpm, the rider could have
a much easier time of it. A continuous force can be applied with soft rotation being supplied. The same logic applies for commercial applications that want lower speeds while maintaining necessary
torque.

• servo gearbox inertia complementing. Today’s servo motors are producing 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 electric motor to the inertia of the load allows for using a smaller motor and outcomes 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 load to the motor is decreased by 1/ratio2.

Recall that inertia may be the measure of an object’s resistance to change in its motion and its function of the object’s mass and shape. The higher an object’s inertia, the more torque is required to accelerate or decelerate the thing. This implies that when the strain inertia is much larger than the motor inertia, sometimes it could cause excessive overshoot or boost settling times. Both circumstances can decrease production collection throughput.

On the other hand, when the motor inertia is bigger than the load inertia, the electric motor will need more power than is otherwise essential for this application. This raises costs because it requires paying more for a electric motor that’s bigger than necessary, and since the increased power intake requires higher working costs. The solution is by using a gearhead to match the inertia of the engine to the inertia of the load.
