Analysis of PM transverse-flux outer rotor machines with different configuration
Dobzhanskyi, Oleksandr; Gouws, Rupert; Amiri, Ebrahim (IEEE, 2017)This paper presents the electromagnetic analysis of two permanent magnet transverse-flux outer rotor machines with and without magnetic shunts. The research started with designing and analyzing a permanent magnet transverse-flux ... -
A comparative study on fault detection and correction techniques on active magnetic bearing systems
Gouws, Rupert; Van Schoor, George (IEEE-Institute of Electrical and Electronics Engineers, 2007)In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ... -
Comparison analysis of electric motors with two degrees of mechanical freedom: PM synchronous motor vs induction motor
Dobzhanskyi, O.; Amiri, E.; Gouws, Rupert (IEEE, 2016)This paper presents a comparison analysis of two electric motors with helical movement of the rotor. These machines are also referred to as machines with two degrees of mechanical freedom. The machines are designed in such ... -
Design considerations of the PM transverse flux linear motor for an urban-type electromagnetic train
Dobzhanskyi, Oleksandr; Gouws, Rupert; Amiri, Ebrahim (IEEE, 2018)This paper presents six different designs of the permanent magnet transverse-flux linear motor applied to an electromagnetic train. The initial design of the motor was modified to improve its magnetic characteristics. ... -
Efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill
Gouws, Rupert (Energy Research Centre, University of Cape Town, 2015)This paper presents an efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill in South Africa. Two scenarios were evaluated: 1) where the induction motor was controlled at ... -
Energy management system for a residential grid-tied micro-grid
Bisschoff, Wilhelm A.; Gouws, Rupert (IEEE, 2015)With the national power grid under tremendous pressure, there are enormous pressure exerted on residential electricity consumers to cut-back on electricity consumption to ensure a reliable supply. This has led to ... -
Experimental results of an asynchronous machine with thermoelectric cooling modules
Gouws, Rupert; Van Jaarsveldt, Heino (2012)It is estimated that globally around 40% of the electricity supplied to the industrial sector is consumed by electric motorised systems and for South Africa around 60% of the electricity supplied is consumed by asynchronous ... -
Intelligent controller for a hybrid energy storage system
Van Jaarsveld, Maarten; Gouws, Rupert (IEEE, 2020)The performance and range of electric vehicles are largely determined by the characteristics of the energy storage system (EES) used. The EES should be sufficiently sized to be able to provide the necessary power and energy ... -
A review on switched reluctance machines for electric vehicle
Zabihi, Nima; Gouws, Rupert (IEEE, 2016)Nowadays, switched reluctance machines (SRM) are gaining interest in the scientific community due to the advantages they offer. The SRM offers an overall efficiency similar to an induction motor of the same rating, since ...
