As an example, consider a person riding a bicycle, with the person acting like the motor. If see your face tries to ride that bike up a steep hill in a gear that’s designed for low rpm, he or she will struggle as
they attempt to maintain their balance and achieve an rpm which will allow 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 will have
a much easier time of it. A continuous force could be applied with easy rotation being offered. The same logic applies for industrial applications that want lower speeds while keeping necessary
• Inertia matching. Today’s servo motors are generating more torque relative to frame size. That’s due to 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 servo gearbox gearhead to raised match the inertia of the engine to the inertia of the strain allows for utilizing a smaller motor and outcomes in a far more responsive system that’s simpler to tune. Again, that is accomplished through the gearhead’s ratio, where the reflected inertia of the strain to the motor is decreased by 1/ratio2.
Recall that inertia may be the measure of an object’s resistance to improve in its movement 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 thing. This means that when the load inertia is much bigger than the motor inertia, sometimes it can cause extreme overshoot or boost settling times. Both circumstances can decrease production range throughput.
However, when the motor inertia is bigger than the load inertia, the engine will need more power than is otherwise essential for this application. This boosts costs because it requires having to pay more for a motor that’s bigger than necessary, and because the increased power consumption requires higher operating costs. The solution is to use a gearhead to complement the inertia of the electric motor to the inertia of the load.
