Torque Calculation of Hysteresis Motor Using Vector Hysteresis Model
This paper presents how to determine the thickness of hysteresis ring of hysteresis motor using the finite element method combined with a vector hysteresis model. From the magnitude and direction of the magnetic field intensity, the magnetization of each ring element is calculated by the vector hysteresis model and the torque can be obtained from the vector sum of each torque of each element or...
متن کاملOn Line Determination of Optimal Hysteresis Band Amplitudes in Direct Torque Control of Induction Motor Drives
In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
متن کاملModeling of a synchronous reluctance machine accounting for space harmonics in view of torque ripple minimization
The paper deals with modeling of synchronous reluctance motor (SynRM) accounting for all phenomena responsible for torque ripple. Based on winding function approach, the proposed model consists in computing self and mutual inductances considering no sinusoidal distribution of stator windings, slotting effect and no sinusoidal reluctance variation caused by the rotor saliency. Then, optimal curr...
متن کاملSpace Vector Modulation Direct Torque Speed Control Of Induction Motor
Various aspects related to controlling induction motors are investigated. Different control strategies are explored. The direct torque control (DTC) strategy is studied in details and its relation to space vector modulation (SVM) is emphasized. An SVM-based DTC strategy is suggested and a controller design based on this strategy is presented. A Simulink model representing the controller is deve...
متن کاملHysteresis Control for Current Harmonics Suppression Using Shunt Active Filter
Recently wide spread of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from ac mains. Current harmonics generated by nonlinear loads such as adjustable speed drives, static power supplies and UPS. Thus a perfect compensator is required to avoid the consequences due to...
