Synchronous Generator With Embedded Brushless Synchronous Exciter
IEEE transactions on energy conversion, 2019A new brushless and permanent magnet less synchronous generator is reported in this work. Contrary to traditional brushless synchronous generators that use an extra machine along with rotating diode rectifier, the proposed machine houses the main and the

The IEEE model of a brushless exciter can be found in many software packages for the simulation of power system behaviour. Yet the model is simplistic and does not represent the exciter alternator accurately. This paper describes the reasons for the inaccuracy of the IEEE representation and proposes an alternative model.

Brushless DC (BLDC) motors, also called permanent magnet synchronous motors, are used in direct-drive applications mainly due to their large torque producing capability. Compared to conventional DC motors, they have no brushes or mechanical commutators, which eliminates the problems due to mechanical wear of the moving parts [68, 74].

The authors design a variable reluctance motor to perform the rotation of clawed-pole rotors. Starting from this singular problem and encouraged by the good practical results they obtained, they have investigated the structure in terms of motor performances for application in variable speed drives.

Brushless DC motor‐driven grid‐interfaced solar water pumping system
IET Power Electronics, 2018A solar water pumping system employing a brushless DC motor drive is presented. The utility grid is utilised as a secondary power source. The total load demand is shared by photovoltaic array and the grid. This results in continuous water pumping.

Brushless induction synchronous generator
2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016In present scenario of renewable energy generation systems, brush-less and magnet-less generators are becoming more popular due to merits such as high reliability, robustness, fault tolerant capability and almost maintenance free operation, etc. This paper deals with a brushless induction synchronous generator (BInSyG), where an induction and a ...

Brushless reluctance-motor drives
Power Engineering Journal, 1987The variable-reluctance or switched-reluctance motor has some remarkable characteristics that make it attractive for dozens of applications. With CAD software now available, and many prototypes established, there should be few technicalbarriers between the laboratory and a number of successful niches in the drives ...

New brushless synchronous alternator
IEE Proceedings - Electric Power Applications, 2003The HB (Haydock Brown) machine combines permanent magnet and wound coil excitation to provide a single-stage brushless alternator. It offers efficient and compact solutions for small-scale engine-driven generator requirements. The simple construction conceals a rather unusual magnetic circuit that displays complex interactions between excitation ...
