What is the point of installing VSD's on conveyor motors that will run only at 60HZ?
Would a "soft starter" be a better choice considering how VSD's can potentially damage non-inverter equipped motors even with the addition of dv/dt filters? Also, VSD's generate harmonics on the power source which can lower power factor along with other ill effects.
It seems to me that vendors are quick to push VSD's without considering their overall impact. Is it a cost issue? acceleration? braking?
Can anyone offer an opinion?
