pwm controlled three phase inverter bridge dimensions?

Answer:

uhmm i basically understand what you are up for, but excuse me a 45kW and a 90kW machine ?? i guess it was the term 'as cheap as possible' which caught my attention in this i'm afraid the electronics is twice as expensive than the motor itself, and i really know no better place than yahoo!answers to ask such a questioni think the cheapes way to get this fixed is to ask a railroad maintanance shop or an elevator manufactorer, just for the fact that they may have already approved designs in use
