In this paper, an electric vehicle drive with a robust and low cost alternating current (AC) induction motor is presented. This approach is applied to an existing commercial utility electric vehicle where previously used direct current (DC) series motor was replaced by the new AC induction motor. The use of three-phase squirrel cage induction motor requires implementing of voltage source invert...

We have taken advantage of the temporal resolution afforded by functional magnetic resonance imaging (fMRI) to investigate the role played by medial wall areas in humans during working memory tasks. We demarcated the medial motor areas activated during simple manual movement, namely the supplementary motor area (SMA) and the cingulate motor area (CMA), and those activated during visually guided...

Recently, digital signal processors (DSP's) are becoming more popular in the area of ac motor control, in particular the induction motor drives. The fast number crunching capabilities of DSP's which are traditionally meant for data processing tasks such as image processing and speech recognition, are being utilised to perform on-line calculation of the ac motor variables, such as electromagneti...

Water pumping using AC motors has become one of the most feasible photovoltaic (PV) applications. Moreover, PV pumping is getting more attention in recent days mainly in remote areas where connection to the grid is technically not possible. Power generation by Photovoltaic is reliable. The operation and maintenance costs are low. The induction motor is more rugged, and maintenance-free motor. I...

Motor AC merupakan motor yang paling banyak digunakan pada industry saat sekarang ini, dikarenakan mempunyai sifat fleksibel. Selain itu terdapat kekurangan salah satunya yaitu diberikan beban maka torsi menjadi besar, hal tersebut dapat mengakibatkan kecepatan menurun. Maka dari penelitian ini bertujuan untuk mengontrolan dan monitoring mesntabilkan berbeban dengan method Fuzzy Logic Controlle...

In the countryside of China, the main power supply mode is 220V single-phase power, which affects the widely application of three-phase agricultural appliances. What’s more, it means a block to the development of modern agriculture. However, frequency converter technique research is focused on three-phase high power frequency conversion technology at present, and there are very few achievements...

Single-phase induction motors are widely used in many applications. Improvements in its performance mean a great saving in electrical energy consumption. A cycloconverter fed variable frequency motor is a typical example of such improvement. In this regard, the paper presents an analysis of the performance and speed control of the split phase induction motor when it is fed with cycloconverter. ...

The efficiency of induction motor drives under variable operating conditions can be improved by predicting the optimum flux that guarantees loss minimization. In this research, a loss-minimization scalar controller, based on determining of modulation index of IGBT inverter-based AC-to-AC converter, which corresponds to optimum flux, is proposed. For this purpose, mathematical models for total p...

Fuzzy logic is recently getting increasing emphasis in soft computing applications in the recent days. This paper presents an application of the fuzzy logic scheme to control the speed of an AC servo system & the same is proposed for a space vector pulse width modulation (SVPWM) inverter-fed permanent magnet synchronous motor (PMSM) drive. Based on the analysis of the PMSM transient response, a...
