Abstract Induction motors (IMs) are the most widely employed electrical due to their robust construction and adaptability. Due versatility wide range of applications, it is crucial examine performance these using a simple but thorough simulation model. In this study, we present models conduct DC test, no-load locked rotor test on three-phase induction motor MATLAB/Simulink. These three tests fu...
1.1 The force F acting on a dipole in an external field H, taken from [24]. 13 1.2 Magnetization torque (a)) without damping, the magnetization M pre-cesses around the H on a constant orbit. With damping (b)) the torque pointing towards H forces the magnetization to align with the external
Background and Aims: Diferences whithin shape and size of hand wrenches in diferent systems could affect the torque applied. Therefore, evaluation of wrenches has been emphasized. The aim of the present study was to compare the torque values of the long and short torque wrenches in different implant systems including ITI, Implantium and Nobel Biocare. Materials and Methods: In this experimenta...
Abstract Due to quick response and large quantity of electric motor torque, the traction wheels battery vehicle are easy slip during initial phase starting. In this paper, a sliding mode control approach acceleration regulation is designed prevent wheels. The wheel ratio used as state variable for formulation system dynamics model. fuzzy algorithm utilized adjust switch function controller. Aft...
this paper presents the method of reducing torque ripple of brushless dc (bldc) motor. the commutation torque ripple is reduced by control of the dc link voltage during the commutation time. the magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (pso) algorithm analysis. the goal of optimization ...
<p><span lang="EN-US">The present paper is directed to achieve a low-cost high-performance self-starting single phase induction motor (SPIM) drive system. A shifted pulse width modulation (PWM) trains feeding the will replace starting and running capacitors. Adaptive sliding mode control, enhance with model reference adaptive control (MRAC), implemented high performance sensorless S...
Introduction: The weak design of hand tools and their disharmony with the user's physical features comprise a major risk factor for upper limb musculoskeletal disorders. Hand-tool related injuries comprise almost 9% of all work-related injuries. The present study was conducted to examine the effect of hand tools' diameter on comfort and maximum hand torque and to estimate the optimal diame...
A switched Reluctance motor (SRM) has several desirable features, including simple construction, high reliability and low cost. However, it suffers from large torque ripple, highly non-uniform torque output and magnetization characteristics and large noise. Several studies have succeeded in torque ripple reduction for SRM using Direct Torque Control (DTC) technique. DTC method has many adva...
