This paper proposes an effective method of energy regeneration during braking for a dc motor or internal combustion(IC) engine. During the braking period, instead of dissipating the kinetic energy in the brake shoes and poles in the form of heat, this energy is recovered using a switched reluctance generator that is mechanically coupled to the shaft of prime mover. Here the DC motor or the IC e...

in this paper, the design and implementation of adaptive speed controller for a sensorless synchronous reluctance motor (synrm) drive system is proposed. a combination of well-known adaptive input-output feedback linearization (aiofl) and adaptive backstepping (abs) techniques are used for speed tracking control of synrm. the aiofl controller is capable of estimating motor two-axis inductances ...

This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-mmf diagram is a generaked version of the flux-linkage versus current (+i) diagram €or switched-reluctance motors. It is illustrated €or switchedreluctance, synchronous-reluctance, induction, brushless ac, brushless dc, interior PM and dc commutator moto...

Torque ripple is a major problem of switched reluctance motor drive system, which causes undesirable vibration and acoustic noise. In this paper, a novel method of torque closed-loop and fuzzy compensation control for the switched reluctance motor drive system based on finite element model is described. In terms of the simulation results and the special characteristics of static torquecurrent-a...

Switched reluctance motors (SRM) becomes increasingly popular due to its simple structure and dependability. It seems have a two-pole configuration. A stator had also centralized coils along each pole, whereas rotor has an iron core only. As result, the switched motor is anticipated be low cost, incredibly robust variable-speed machine. Because only made up of laminated coils, performance heavi...

This paper presents experimental results for two adaptive nonlinear controllers applied to a variable reluctance motor (VRM). The rst controller requires both rotor position and velocity (full state) feedback, while the latter is an observer-based backstepping-type output feedback controller, requiring only rotor position measurement. Velocity for the full-state controller is estimated using a ...

The Electromagnetic Aircraft Launch System (EMALS) is being developed utilizing electrical and electronic technologies. EMALS is emerging in order to replace the existing steam catapult on naval carriers. Recently, the double-sided linear launcher has drawn increasing attention of researchers. This paper presents the design and analysis of the Linear Hybrid Reluctance Motor (LHRM). This new mot...

Electric vehicle seems largely based on electrical machines. Finding the best motor type be important for having more performances and a transport system robustness. In this work, we present an analytical model of synchronous machine with variable reluctances in linear saturated modes. The angular position rotor (θ) phase current (i) will beused as parameters. allow us to determinate its magnet...
