The paper deals with an overview regarding the implementation of individual urban transportation using reluctant motor driven electric bicycles. A particular case of Cluj- Napoca city is taken as reference. Study of opportunity, state of the art in the field of electrical driven bikes and a proposed solution for electric motorizing in this field are(More)
The paper presents the aspects regarding FEM analysis of a reluctant motor for direct driving of the light electric vehicles. The reluctant motor take into study is of special construction suitable for direct drive of a light electric vehicle. It is an inverse radial reluctant motor, with a fixed stator mounted on front wheel shaft and an external toothed(More)
An important challenge for energy systems today is reducing dependency on fossil fuels, while handling increasing penetration levels of intermittent renew abies such as wind and solar power. The efficient consumption of energy is a vital mater for a sustainable energy system. A significant part of energy is used for space heating, space cooling, and(More)
Following a comparison to one-phase and two-phase-on, this paper brings contributions to the analysis of an 8/6 Switched Reluctance Motor (SRM). It is a common variable-reluctance motor with and internal salient 6-pole rotor, which has no conductors or magnets, and an external 8-pole stator with concentrated coils, which allows earlier winding and shorter(More)
The paper is the first attempt to 3D approach of a special reluctance motor for the implementation of individual urban transportation. The motor is of inverse construction - inner stator fixed on front wheel shaft and outer rotor linked to wheel rim. This in-wheel motor ensures fundamental requirement of a direct gearless driving the light electric vehicles(More)

The paper deals with an adaptive speed controller design for a brushless DC motor drive. The controller structure include also a load-torque estimation approach in order to achieve a robust accurate path tracking. The design procedure is based on the fieldoriented control loop so as the controller itself will has two components: a two degree of freedom(More)
Energy systems are faced with the challenges of reducing dependency on fossil fuels, while handling increasing penetration levels of intermittent renewables such as wind and solar power. At the same time, the efficient consumption of energy is vital for avoiding the impacts from increasing fuel prices. A significant part of this challenge may be dealt with(More)
