For example temperature sensor features or electric and mechanical interface properties at component level. Sehen Sie sich das Profil von kurt doppelbauer auf LinkedIn an, dem weltweit größten beruflichen Netzwerk. All common stator and rotor windings are taken into account.

All rights reserved.Università degli studi di Cassino e del Lazio Meridionale For improved results, the winding design in the finite element analysis (FEA) considers individual wires and parallel wire strands.

Damit ist auch erstmals eine genaue Untersuchung der Wechselstromkommutierung mglich. Four real-time capable st...Inverter nonlinearities and machine spatial harmonics yield unwanted machine current

However, the influence of temporal current harmonics, especially of the high-order temporal harmonics caused by pulse width modulation voltages from an inverter, lacks attentions....Stator winding faults are one of the major limitations of the lifetime and reliability of electrical machines.

Even larger turbine sizes are managing to pave their way from studies to market.

The best utilization of the el...This paper describes the iron losses calculation of an axial flux machine with yokeless and segmented armature structure based on the limited 3D FEA results corresponding to one-sixth electrical period. Particularly, three-phase permanent magnet synchronous machines (PMSMs) have significant drawbacks in terms of fault tolerant...It is well-known that spatial field harmonics will cause high eddy current losses in surface-mounted permanent-magnets (PMs) especially for the fractional-slot PM motors.

State of the art current control methods usually ignore these effects and hence do not produce optimal results in t...The paper presents the numerical calculation of iron loss in a novel axial flux machine with segmented armature torus topology is researched. The purp...This paper investigates the cogging torque caused by manufacturing tolerances through analytical, finite element analysis (FEA) and experimental methods.

Compared with conventional radial flux machine, the main flux path in CPTFM is three dimensional and tr...This paper presents the performance comparison among three different topologies of the permanent magnet synchronous machine, namely a transverse flux permanent magnet machine with flux concentration and claw pole structure, an axial flux machine with segmented armature torus structure and a conventional radial flux machine with embedded permanent m...This paper is about the mechanical design and analysis of a yokeless and segmented armature axial flux permanent-magnet (PM) synchronous machine, which consists of two external rotors and an inner stator. Test data for motors where copper has simply been substituted for aluminum with no change in design are presented for a series of motors built in India for pumping water for agriculture and two industrial motors are descr...Performance of several motors where copper has been substituted for aluminum in the rotor squirrel cage is reported. Different brush types and their influence on commutation can be calculated. To address them and without hindering the customers’ expectation, the solution are various and multiple. As a result of the...Synchronous machines with displaced reluctance axis promise improved performance due to the optimized utilization of reluctance and synchronous torque.

As many approaches exist to estimate the ohmic losses in the windings of a motor and addi...This paper examines the possibility of protecting the magnets of permanent magnet electrical machines against demagnetization in case of a sudden three-phase short circuit at the terminals of the stator winding. This can lead to strong mutual coupling between the flux paths of the motor phases and thus an isolated modelling of each motor phase of the SRM is imprecise. The key challenge is the difficulty in sl...Confronted to new social, environmental and economic challenges, the automotive sector is currently facing a major shift of its history.

This paper presents a predictive control method to precisely control the dynamics of these machines.

The subject of this paper is a variable reluctance resolver model to...Rotor and stator stacks consist of laminated electrical steel sheets and represent the essential components of an electric drive. The relationship between pr, pf and pa is pr = pf + pa. Prof. Dr.-Ing.
