- Experimental study of rotor eddy-current loss in high-speed PM synchronous machine.
- Testing of Inconel718 and carbon-fiber retaining sleeves.
- Effect of slot opening width on rotor eddy-current loss.
- Magnetic shielding effect on rotor eddy-current loss.
The goal of this paper is to analyze and evaluate the eddy-current losses due to stator slotting in conductive and non-conductive retaining sleeves mounted on the rotor of a high-speed SMPMSM: 60Â kW, 10Â kRPM, designed for an aeronautical application. Roughly speaking, there are two groups of sleeves: composite sleeves (carbon-fiber or fiberglassÂ +Â resin) and metallic sleeves (Inconel718, titanium, stainless steel). For both types of sleeves losses are estimated by two means: a 2D finite-element model (AnsysMaxwell) and experimental tests. According to test bench results, the use of a composite sleeve reduces losses by 330Â W (370Â W found with the FEM), showing reduction equal to 0.6% of the machine's rated power. The eddy-current losses in the magnets are equal to 60Â W. The final section of the paper proposes an optimization study of eddy-current loss and an analysis of the shielding effect induced by the high-conductivity sleeve (aluminum, etc.).
