Don't be drawn into the power factor on the supply side as issue. In addition to this, as stated earlier in the thread you don't have to consider capacitors on the output. What is important is the step-up transformer on the output, the transformer has to be suitably designed to take care of the...
UKPete,
I have assumed that the motors have been rated for class B temp rise (90degC), with class F insulation.(115degC).
Motors are generally designed Class B temp rise, Class F insulation and for 40degC ambient, if they have to operate in temperatures above these conditions considerations...
What are the ambient temperature requirements? 5 to 45 degC
What is the operating speed? 1800 rpm
Is this being driven from a variable speed drive? No
Is water readily available? Yes, soft water (treated, closed loop)
What are the noise requirements? 85 dB measured one meter from...
SparksZA,
What are the ambient temperature requirements?
What is the operating speed?
Is this being driven from a variable speed drive?
Is water readly available?
What are the noise requirements?
The above factors will dictate the suitability of the cooling method.
RMG.
