   Comparison of soft-landing position control and energy minimization performance of two fluid-control solenoid valves
By J.R.M. VAN DAM [View]
[Download]

Abstract: This paper considers low-energy solenoid actuators for application in an automotive fluid-control valve. A permanent magnet-biased (PMB) topology is compared to a classical reluctance actuator (CLA) using magnetostatic simulation data regarding their merits in closed-loop control position tracking, soft-landing, and energy consumption. The PMB topology achieves similar position-tracking as CLA, with the added benefit of reducing the energy demand by at most 63\%.

   Design and Optimization of E-Core Integrated Flux-Switching Motor-Compressor
By Hao DING [View]
[Download]

Abstract: An integrated motor-compressor is designed in this work which can provide motoring function withcompressing function at the same time. The integrated motor-compressor needs to be capable of driving multiple stages of the axial-flow compressor. An E-shaped stator core with large slot opening and less magnet is implemented for the integrated motor-compressor to achieve this requirement. The proposed machine with E-shaped stator core is compared with 12-slot 10-pole integrated motorcompressor on both electromagnetic and thermodynamic aspects. Design optimization on the slot opening and mid-tooth thickness of the E-core stator is investigated. The slot/pole combinations of the E-core-based integrated motor compressor are also analyzed.

   Efficiency and loss distribution comparison for a motor drive system with and without LC-filter
By Radu LAZAR [View]
[Download]

Abstract: The paper compares the efficiency of drive systems with and without LC-filter by means of laboratory measurements. Each component's efficiency is measured simultaneously together with the overall system efficiency. Different conditions like motor speed, loading, PWM strategy and switching frequency are varied during the experiment. The results are commented upon and conclusions are drawn

   Power and Efficiency of Salient Pole and Flux Barrier Type Synchronous Reluctance Machines in Low Power Drives
By Matthias HOFER [View]
[Download]

Abstract: In this paper synchronous reluctance machine topologies are investigated regarding power and efficiency for a low power industrial drive. Starting from an existing standard induction motor two rotor types, flux barrier and salient pole, were designed for a wide speed range of the electric drive. By adaptation of the stator winding the drive requirements are met for both topologies. In this work the focus is set to the behavior in the flux weakening region for utilizing a high power capability and high efficiency in an application. Both rotor types are analyzed by finite element methods and show different characteristics. The salient pole machine is able to provide a power at maximum speed more than two times higher than the flux barrier type and shows a much broader constant power speed range. Further, because of nearly constant machine saliency, the part load efficiency of the salient pole rotor is higher, although the flux barrier machine has a higher efficiency at maximum torque. Experimental results are presented and confirm the higher torque per ampere characteristic of the salient pole machine because of its lower quadrature axis inductance. The torque vs. speed limit during flux weakening shows the higher performance of the salient pole rotor. Thus, in this application at driving cycles with major operation time at high speeds the salient pole rotor is preferred.
