Automated testing system for variable speed drives and synchronous reluctance motors based on IEC-60034-2-3 requirements

Sinkroni reluktantni motori sve više se koriste u industriji zbog visoke korisnosti i otpornosti na industrijske uvjete. U radu je opisan postav za automatizirano ispitivanje gubitaka i korisnosti sinkronih reluktantnih motora po zahtjevima norme IEC-60034-2-3. Sustav automatizirano prolazi kroz radne točke definirane normom i zapisuje mjerene podatke u odvojene blokove podataka za svaku radnu točku. Korišten je napredni sustav za akviziciju podataka Dewesoft Sirius. Zahvaljujući automatizaciji postava, ispitivanje je standardizirano i ponovljivo. Ispitivanje je provedeno za kombinacije pet sinkrono reluktantnih motora i tri frekvencijska pretvarača za napajanje motora. Synchronous reluctance motors are increasingly used in industry due to their high efficiency and durability in industrial conditions. The paper describes a setup for automated loss and efficiency testing of synchronous reluctance motors according to the requirements of the IEC-60034-2-3 standard. The system automatically runs through the operating points defined by the standard and records the measured data in separate data blocks for each operating point. An advanced Dewesoft Sirius data acquisition system was used. Thanks to setup automation, testing is standardized and repeatable. The test was performed for combinations of five synchronous reluctance motors and three frequency converters powering the motors.
