As an example, consider a person riding a bicycle, with the individual acting like the motor. If that person tries to ride that bike up a steep hill in a gear that’s designed 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 shift the bike’s gears into a acceleration that will create a higher rpm, the rider could have
a much easier time of it. A constant force could be applied with simple rotation being offered. The same logic applies for industrial applications that want lower speeds while maintaining necessary
• Inertia complementing. Today’s servo motors are generating more torque in accordance with 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. Using a gearhead to servo gearbox better match the inertia of the motor to the inertia of the strain allows for using a smaller motor and results in a far more responsive system that is simpler to tune. Again, this is attained through the gearhead’s ratio, where in fact the reflected inertia of the strain to the motor is decreased by 1/ratio2.
Recall that inertia is the measure of an object’s level of resistance to improve in its movement and its own function of the object’s mass and form. The higher an object’s inertia, the more torque is required to accelerate or decelerate the thing. This means that when the strain inertia is much larger than the motor inertia, sometimes it could cause extreme overshoot or increase settling times. Both circumstances can decrease production line throughput.
However, when the electric motor inertia is bigger than the load inertia, the electric motor will require more power than is otherwise essential for the particular application. This improves costs since it requires having to pay more for a electric motor that’s larger than necessary, and since the increased power usage requires higher working costs. The solution is by using a gearhead to match the inertia of the motor to the inertia of the strain.
