Electric and hybrid electric vehicles are attractive candidates for sustainable transportation due to its higher efficiency and low emission. The critical choice on the electric motors is its capability of motoring and regenerative braking characteristics. Switched reluctance machines are viable candidate as with proper control and extended constant power range operation replacing the multi-gea...

This contribution is a brief review of the status of hybrid baryons, which are hypothetical baryons that incorporate a gluonic excitation. We first summarize the status of hybrid mesons, since this closely related topic has seen considerable recent activity with the identification of two exotic candidates. Next we review theoretical expectations for the masses and quantum numbers of hybrid bary...

This paper deals with the potentials of a Hybrid-Excitation Permanent-Magnet (HEPM) machine. The HEPM machine is characterized by rotor including both permanent magnets (PMs) and excitation coils. PMs produce constant flux at air gap machine, while an current supplied so as to regulate such flux. A increase could be necessary during transient overload operations, decrease useful Flux-Weakening ...

This paper presents the design and research results of a claw pole machine with hybrid excitation. is excited by permanent magnets an electromagnetic coil. Both excitation sources are located in rotor machine. Additionally, made laminated core. approach facilitates process its construction enables implementation even very complicated structure rotor, which would be difficult case making from on...

this paper considers the problem of scheduling hybrid flowshops with machine availability constraints (mac) to minimize makespan. the paper deals with a specific case of mac caused by preventive maintenance (pm) operations. contrary to previous papers considering fixed or/and conservative policies, we explore a case in which pm activities might be postponed or expedited while necessary. regardi...
