The paper presents the principles of the decoupling control of the phase voltage in the Switched Reluctance motor drive for the direct-drive joint of the robot. The motor drive system elements, such as the structure of the three-phase 6/10 structure Switched Reluctance motor and the rotor position, the main circuit topology of the three-phase bifilar winding power converter and the pulse width ...

Abstract— The Switched Reluctance Motor (SRM) drive has evolved as an alternative to conventional motors in variable speed drives because of advantages like simple and rugged structure, absence of rotor winding, adaptability to harsh environments and high speed operation. This paper presents the speed control of Asymmetrical converter fed 4 phase 8/6 Switched Reluctance Motor drive using PWM co...

This paper deals with the modelling and simulation of the squirrel cage induction motor by taking into account all space harmonic components as well as the introduction of the bars skew in the calculation of the linear evolution of the magnetomotive force (MMF) between the slots extremities. The model used is based on multiple coupled circuits and the modified winding function approach (MWFA). ...

In order to decouple traditional levitation windings and armature windings, a new selfdecoupling magnetic levitation generator (SDMLG) is proposed for wind turbines. This new generator adopts double-stator structure. The armature windings are in the outer stator, and the levitation windings are in the inner stator. The rotor is made of a distributed hollow structure, so that it can effectively ...

Modern analysis techniques for electrical machines are either analytical or use finite element analysis. Both methods are implemented using computational techniques to solve the magnetic circuit and produce performance predictions. This paper puts forward a steady-state impedance matrix method for analysing a split-phase induction machine that is at the leading edge of analytical modelling of i...

Modeling of convection heat-transfer at the end-windings for thermal networks using lumped-parameters has been widely discussed in literature. Unfortunately, resulting coefficients are highly influenced by end-winding shape, area vicinity end-windings, cooling method this region (if any), as well size and power machine. This makes it extremely difficult designer to choose a suitable coefficient...

Control of commutation of switched reluctance (SR) motor has been an area of interest for researchers for sometime now with mixed successes in addressing the inherent challenges. New technologies, processing schemes and methods have been adopted to make sensorless SR drive a reality. There are a number of conceptual, offline, analytical and online solutions in literature that have varying compl...

A novel brushless double rotor machine (BDRM) is proposed in this paper. The BDRM is an important component in the brushless compound-structure permanent-magnet synchronous machine (CS-PMSM) system, which is a promising technology for power-split hybrid electric vehicle (HEV) applications. Compared with common double rotor machines, the brushes and slip rings required by rotating winding have b...

This paper presents a new and precise mo del for different kinds of eccentric rotor of rotating machines based on polar signals concepts. Eccentricity faults in each static, dynamic and mixed cases cause that the non-uniform air-gap of machine be established. The applied model using polar signals for eccentric rotors have removed the usage approximations in two recent decays. Eccentricity coeff...
