I have an application where we need to put a few ac motors on a small machine. The motors are 3/4hp and will be speed controlled with a vfd. The size of the inverter duty motors is a big concern as the machine is pretty small. Is there a chance that inverter duty motors are really not needed? On these machines, the motors are speed scaled with an analog signal but the speed is constant per product - much like controlling the speed of a conveyor. Anyone have experience with this? The only literature I can find on the need for inverter duty motors is put out there by the manufacturers of these same motors...
