Hi again Dana & Wrenches. I heard back from the fellow, along with an updated document about running FP washers on inverters. Hope there's some useful info here. ______
Hi Michael, Good to hear from you. The attachment was still essentially correct. I have had the Laundry electronics control guru look at this and he has made few minor updates. I was quizzing him up as to why he had only ± 5% tolerance on the frequency - considering the system rectifies the mains into DC then chops it up again for the motor - and the electronics for the 50Hz 230 V version is essentially the same but without the voltage doubling. He points out that some of the washer range (still) has pumps with shaded pole motors and that on a 50 Hz supply the 60 Hz pumps draw too much current. I.e. the induction is insufficient to limit the current that far from the pump motor's design frequency. I have copied this to Scott Davies. (714.421.8574) He is in our Huntington Beach (Orange County) office. He looks after sales and marketing for North America.
