Rotor flux and torque of an induction motor (IM) are decoupled to obtain performance of DC motor. The decoupling strategy has been developed in terms of stator current components where the core loss is neglected. Many different controllers including fuzzy logic controller (FLC) with neglecting core loss have been designed to control the speed of induction motor. The outcome of investigation abo...

In this study, direct torque control (DTC) of induction motor is evaluated based on space vector modulation (SVM).DTC is a method to control machine with utilizing torque and flux of motor controlled.Direct Torque Control (DTC) is known to produce fast response and robust control in ac adjustable speed drives. However, in the steady-state operation, notable torque, flux and current pulsations o...

The objective of this paper is to apply the Hybrid Efficiency Loss Minimization control scheme [1] into a FOC controlled ACIM motor drive in order to improve the fast on-line loss minimization control through flux control,.

A new permanent magnet design for axial flux interior permanent magnet (AFIPM) motor is described in this paper. Poleshoes are traditionally used to produce sinusoidal flux linkage and sinusoidal EMF especially in the case of radial flux synchronous machines. Poleshoes are not a practical solution in the case of axial flux PM machine. The use of poleshoes in the production of sinusoidal back EM...

In the presented paper, a sensorless driver circuit is designed, constructed and tested to control two types of three-phase Switched Reluctance Motor (SRM). The presented control algorithm has three steps. In the first step, the SRM is controlled by an open-loop method. In the second step, mathematical model of the SRM phase, motor parameters and flux-current-rotor position relation are used in...
