Thermal and efficiency analysis of a single phase induction motor with Peltier devices
(Multi-Science Publishing, 2012)
We present the results obtained from the thermal and efficiency analysis of a single phase induction motor with Peltier devices. A single phase induction motor is completely simulated in SolidWorks® and Matlab® Simulink®. ...
Comparative study of steam vs hot water as primary heat transfer medium for a laboratory scale two-tank heated system
The need exists for a benchmark multi-domain practical system that could emulate typical process faults for the purposes of condition monitoring. A proposition was made to develop a heated two-tank system, due to its ...
Intelligente beheer van ’n hernubare, energiedoeltreffende tenk vir melkboerderye
To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient bulk storage tank using solar power was designed. The system uses thermoelectric cooling modules as a supporting cooling ...
A self–sensing active magnetic bearing based on a direct current measurement approach
Active magnetic bearings (AMBs) have become a key technology in various industrial applications. Self-sensing AMBs provide an integrated sensorless solution for position estimation, consolidating the sensing and actuating ...
A review on thermoelectric cooling modules: installation design, performance and efficiency
(Academic Journals, 2013)
A thermoelectric cooling module (TECM) is defined as a solid-state heat pump and present advantages (for example, no moving parts and no harmful gasses) over other refrigeration technologies. However, to optimally use ...
Analysing two control methods of shunt active filters for unbalanced load
(Staff Research Council of Yeshwantrao Chavan College of Engineering (YCCE) , Nagpur, India, 2014)
A three-phase shunt active filter is used for current and/or voltage unbalance compensation. Two control schemes with two different theory, instantaneous power theory and Generalized Fryze are considered to compensate the ...
Efficiency analysis of a three-phase power transformer
(Crown Publications, 2015)
Efficiency analysis of an induction motor with direct torque and flux control at a hot rolling mill
(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 ...
Nie-indringende monitering van elektriese kabels in die industriële sektor om onklaarraking en kragonderbrekings te beperk
Condition monitoring of electrical cables can prevent cables from failing prematurely. Partial discharge (PD) is the main source for degradation of the insulation material of medium-voltage cables. The well-known capacitor ...
Development of an axial suspended AMB experimental bench for load and disturbance tests
(UNAM (Universidad Nacional Autónoma de México), 2015)
This paper provides the development of an axial suspended active magnetic bearing (AMB) experimental bench for load and disturbance tests. This test bench must be capable of levitating a 2 kg steel disc at a stable working ...
