Development of Somaloy Components for a BLDC Motor in a Scroll Compressor Application
Persson Mats,Nord Goran,Pennander Lars-Olov,Atkinson Glynn,Jack Alan 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
Electric scroll-compressor drives are commonly used for e.g. home appliance cooling units. The recent development of hybrid cars with internal combustion engine in combination with electrical propulsion requires new solutions to be able to cool the passenger compartment of cars at stand-still. Both application areas demand efficient motor drives to reach good economy and efficient use of limited battery power as well as competitive volume/weight for a given output. The BLDC motor is a controllable and efficient solution. A major part of the motor is the soft-magnetic core. The powder based Somaloy® material shows high resistivity and induction as the result of engineered iron particles with in-organic coating. The unique features of compacted Somaloy® components can be utilized to enhance the shape and total volume of the BLDC motor with at least maintained efficiency compared to the use of traditional laminated steel sheet cores. A careful design of the Somaloy® components can also simplify assembly and positively influence the coil configuration. This study shows a comparison between a typical laminated BLDC motor and a redesigned, Somaloy® based version adapted for a scroll-compressor application.
