The efficency will depend on the number of stages, as the number of stages increase the time constant to charge the mulitiplier and losses will increase exponentially. In a multiplier with a large number of stages you can encounter a condition known as a "starving multiplier" where the losses...

As a general rule, VFD's are optimized for 3phase motors. That being said within a few constraints a VFD can be used on a single phase motor as well provided a few things are true: #1 motor should be a perminant split capacitor type #2 motor should NOT have a start capacitor or start winding or...

That solution would not only double the cost by duplicating every component, but would double the physical size as well. Everything would have to be duplicated, interstage cooling, driers, etc. It is not a compressor issue, the compressor is well within it's ratings running at 3600rpm, it's...

the load is relatively contstant torque at any speed.(air compressor) The reason for this arrangement is to be able to take advantage of a 220v line when it is available (more output via double rpm) as opposed to a regular dual voltage motor which will not produce more output at 220V, just draw...

If I did that I would not need a VFD, only a dual speed motor, and use an autotransformer (don't even need isolation). The reason for the second VFD is to eliminate the need for a transformer that has to handle 3kW (using a dual voltage 3 phase motor). I am trying to eliminate these extra...

Hi I need to fill a strange application. Application is for a piece of mobile equipment that is capable of operating at any speed. It is currently running with a dual voltage single phase capacitor 115/230 motor running 1800 rpm synchronous induction motor approx 1.6HP continuous duty rated...
