Optimal switching-flux motor design and its cogging effect reduction
(IEEE, 2017)
This paper presents an optimal switching-flux motor design in terms of cheap cost, simple manufacturing process, and easy maintenance. The high cogging effect and its impact on the performance of the machine is studied by ...
Comparison analysis of AC PM transverse-flux machines of different designs in terms of power density and cost
(IEEE, 2017)
This paper compares four different configurations of PM transverse-flux machines. The permanent magnet transverse flux machines with: internal rotor; outer rotor with magnetic shunts; double coil; and outer rotor without ...
3-D Finite element method analysis of twin-armature permanent magnet motor with two degrees of mechanical freedom
(Springer, 2016)
In this paper, the authors present a twin-armature rotary–linear permanent magnet (PM) motor. The stator consists of two armatures which generate two rotating magnetic fields and the rotor consists of two rigidly coupled ...
Intelligent controller for improved efficiency of micro wind turbine generators
(IEEE, 2016)
Due to an ever increasing demand for electricity Eskom is struggling to cope, which inevitably leads to load shedding. Although this is a minor inconvenience for residential users, the effects can be detrimental for ...
Solar power pumping system for domestic appliances
(IEEE, 2014)
With the world encountering huge pollution problems, use of renewable energy is being encouraged in place of fossils fuels for electricity generation. On such renewable energies is solar power. Solar powered systems are ...
Study on energy losses in industrial sector caused by low actual efficiency of induction motors
(IEEE, 2014)
This paper presents a study on energy losses in the industrial sector caused by low actual efficiency of induction motors (IMs). The main reasons are discussed and an efficiency analysis of a 3-phase induction motor, ...
Condition monitoring of medium voltage electrical cables by means of partial discharge measurements
(SAIEE, 2014)
The purpose of this paper is to discuss condition monitoring (CM) of medium voltage
electrical cables by means of partial discharge (PD) measurements. Electrical cables are exposed to a
variety of operational and ...
Design of a transmission line monitoring solution for an unmanned quadcopter
(2014)
Eskom owns thousands of kilometres of transmission lines that need to be inspected in order to plan maintenance. Current methods of inspection are costly and ineffective and could pose safety risks. Systems already developed ...
Integration of battery and super-capacitor banks into a single-power system for a hybrid electric vehicle
(IEEE, 2016)
This paper presents a study on a hybrid electric vehicle for mines and other industrial sectors. The power supply system of the vehicle is designed by combining two sources of power: a battery and super-capacitor banks. ...
Novel measurement and verification of irrigation pumping energy conservation measures under incentive-based programmes
(ERC, UCT, 2018)
In most countries the agricultural sector, especially crop irrigation, is a considerable energy consumer. Farm irrigation studies in South Africa showed that energy and water is wasted on a large scale and there is a large ...
