In the actual operation, the stator magnetic slot wedge is vibrated by the large alternating electromagnetic force, which causes the stator magnetic slot wedge to defect and then affect the starting performance and efficiency of motor.
Recently, flux-switching permanent magnet (FSPM) machines, particular for multi-phase topologies have attracted wide interests due to the merits of high power density, strong fault-tolerant capability, and high efficiency, etc.[1]-[4]. However, the reliability of FSPM machines has never been reported although it is an important issue for electrical machines [5]. Hence, in this paper, a reliability...
Event-based computation is a well-established way of reducing the complexity of neural modelling, often used as an enabling step towards the simulation of large neuronal ensembles. Recently, the advent of the physical memristor has provided the scientific community with a stand-alone nanoelectronic device that exhibits strongly ‘synapse-like’ behaviour and can be used in general neural modelling....
Numerous circuit topologies have been proposed for divide-by-m injection-locked frequency dividers (ILFDs), most of which have been optimized for division by even numbers, especially divide-by-2. It has been more difficult to realize division by odd numbers, such as divide-by-3. This paper describes a CMOS injection locked frequency divider (ILFD) that can operate equally well in both divide-by-two...
The model of steam turbine based on multi-modules high temperature gas-cooled reactor is proposed. A series of procedure is adopted to reduce the model error. Simulation analysis on the presented model is conducted to verify the precision and suitability, and the influence of different regulation methods on the output power is studied.
This paper presents a method to evaluate capacity probability distributions of aged power equipment. The method can be applied to any equipment with multiple components. Both repairable and aging (end-of-life) failure modes are modeled. The capacity probability distributions vary over time since the unavailability due to component aging failures increases with the age. The probability distributions...
Aimed at the problems, such as the poor synchronization performance of heavy crane being operated coordinately and huge amounts of on-line calculation using the existed relative coupling strategy, a position synchronization controller based on adjacent relative coupling strategy and backstepping is designed. The simulation model is constructed in Matlab/Simulink environment, and the Simulink results...
The physical fields of synchronous generator are very complicated because of the coupling of electromagnetic field, fluid field, and thermal field. In this paper, a large synchronous generator is taken for an example and the three types of fields are calculated. First, the mathematical model and physical model of the 2-D electromagnetic field are determined by which the losses in each part of the...
