Direct Torque Control Based on a Fast Modeling Method for a Segmented-Rotor Switched Reluctance Motor in HEV Application

A New Skewed-Rotor-Pole Switched Reluctance Motor Design

This paper considers a new switched reluctance motor (SRM) structure aiming at high starting torque with low volume. For some applications such as EVs (Electrical Vehicles), the motor volume and starting torque is a critical point in its design. In many methods, reducing the motor volume causes reduction in starting torque and decreases the motor efficiency. Unlike conventional SRMs, the rotor ...

Direct Torque Control of Switched Reluctance Motor Drives

A New Doubly Segmented Structure for Switched Reluctance Motors with High Torque Capability

In this paper, a new magnetic structure for switched reluctance motors is presented. In this structure, both stator and rotor has a segmented topology and there is no magnetic flux path between two stator/rotor segments or any possible combination of them. The proposed segmental structure may be considered with different number of phases as well as different number of segments per phase for any...

A NEW METHOD TO REDUCE TORQUE RIPPLE IN SWITCHED RELUCTANCE MOTOR USING FUZZY SLIDING MODE

This paper presents a new control structure to reduce torque ripple in switched reluctance motor. Although SRM possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. In this paper another control loop is added and torque ripple is de ned as an objective function. By using fuzzy sliding mode strategy, the DC...

Direct torque control of 4 phase 8/6 switched reluctance motor drive for constant torque load

Abstract. The Switched Reluctance Motor (SRM) Drives have attracted the attention of many researchers in the recent past because of advantages like simple mechanical structure, adaptability to harsh environments like coal mining etc. But it has one main disadvantage of high torque ripple due to its double saliency structure. The Direct Torque Control (DTC) technique can minimize the torque ripp...
