I am looking to purchase vibrating conveyors and have 3 different vendors that have quoted. There is a large Hp difference in the vendors as for example for 1 of the conveyors, one quoted 90p, another 80Hp and the other 2 (20 Hp) motors which equal 40 Hp. Thus one vendor is 1/2 or less than the others but the explanation I was given is the use of unbalanced motors uses less Hp than a balanced motor and it is less expensive.

Can someone explain the balanced vs unbalanced motor in simple language and adivse whether the above can make sense?

Thank you.
