Default Wo ist Ihr Drehphasenkonverter ?





SRM Dr. K.K. suggest reverse engineering the drive which was designed for a washing machine which to us runs a relatively relatively high voltage and low amperage so while it will drive a motor with lower turns count its wimpy fet wont handle what we do amp wise. The IC has no identifiers so re work is a task. You see I have the rotary phase convertors. One is already built for 20 hp 240v 3 phase support of a single 240 line .
The motor is a 20 hp Blador The other will support 10 hp which is plenty of overhead for a 5hp industrial VFD. Having that on my bench will allow testing of many concept motors like ISCAD, IM, SRMs , Synchronous SRM's, PMDC, PMACS and quite possibly the flux switching machine I designed. But we can definitely drive this SRM with the fully programmable VFD.


Ich kann die Wicklungskrone des Königs definitiv verbessern, aber statische Messungen müssen an der neuen Maschine durchgeführt werden, um zuerst in die vfd Motorparametertabelle einzugeben. Dazu ist ein Indexer mit einem Gradrad und einer isolierten Transformator-Stromversorgung erforderlich.
