“…Lateb et al [5] also compare different types of solid rotor constructions to a laminated rotor topology, and it is reported that the laminated rotor topology has 2-3% higher efficiencies than the different solid rotor constructions, as well as a higher power factor. Similar results were reported by Ikeda et al [21], who experimentally compared a solid caged rotor topology to a laminated rotor topology for a 200kW, 12krpm machine.…”

“…The stack and the rings are tightened by the tie rods, also distributed at the periphery of the core and screwed into the shaft ends. This patented technology is being used commercially by Converteam SAS (now GE Energy) [5]. This motor is commercially called MGV (moteur grande vitesse), in the 3 to 30MW range from 6000 to 18000 rpm for compressors in the oil/gas industry.…”

“…Electric high speed drives with magnetic bearings allow the elimination of the gearbox and of the entire lubrication oil system, which leads to increased safety, increased efficiency, increased availability as well as to reduced operation and maintenance costs. Thus, the electric high speed drives are the most environmental friendly compressor drives [5]. The layout and rotor of a 10MW 20000rpm Induction Machine developed by Converteam (now GE Energy), and used within such an application are shown in Fig.…”

The thermodynamic analysis of an electrically supercharged Miller Cycle gasoline engine with early intake valve closing

et al. 2019

View full text Add to dashboard Cite

Electric superchargers are able to improve the thermodynamic process of gasoline engines by selfadapting running state to dominate intake air in all operation conditions. This paper proposes a novel approach for electrically supercharged Miller Cycle with early intake valve closing based on thermodynamics to settle the fuel economy problem of gasoline engines at low load operations by taking advantages of the domination of electric superchargers to intake air. Electrically supercharged Miller Cycle with early intake valve closing was realized by matching an electric supercharger, redesigning the inlet cam, and setting the intake valves closing before bottom dead center while keeping intake valves opening constant. An over-expanded engine cycle is attempted to be used to promote thermal efficiency by increasing geometric compression ratio, in addition to maintaining the effective compression ratio. Here, it has been attempted to systematically analyze the law of the energy losses of the electrically supercharged Miller Cycle gasoline engine with early intake valve closing using a reliable thermodynamic model from the perspective of heat engine. The results indicate that electrically supercharged Miller Cycle with early intake valve closing could improve the thermal efficiency of gasoline engines by significantly decreasing the pumping and exhaust losses.
