Vernier reluctance machine (VRM) with dc field coils in stator is a competitive rare-earth-free design for variable-speed industrial applications due to its robust structure and controllable excitation, while torque density relatively disadvantageous. To address this issue, article proposes new armature winding method VRM across two teeth. The key break the traditional principle based on flux m...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

The switched reluctance motor is a simple and robust machine, which has found application over a wide power and speed ranges in different shapes and geometries. This paper introduces a new configuration for a two phase unidirectional switched reluctance motor/field assisted generator. The proposed novel motor/generator consists of two magnetically independent stator and rotor sets (layers), whe...

This paper presents a magnetic field analysis of an original Doubly-Excited Brushless Reluctance Machine (DEBRM). The stator of the DEBRM consists of two sets windings with different pole numbers. The rotor is an axially laminated structure with a pole number different from either of the stator windings. The finite element method is applied by which the magnetic vector potentials under no-load ...

Fault tolerance is an obligatory feature in safety critical applications (aeronautical, aerospace, medical and military applications, power plants, etc.), where loss of life, environmental disasters, equipment destructions or unplanned downtimes must be avoided. For such applications, a novel bio-inspired motion control system is proposed. All its three components (the switched reluctance machi...

Torque ripple minimization of switched reluctance motor drives is a major subject based on these drives’ extensive use in the industry. In this paper, by using a well-known cascaded torque control structure and taking the machine physical structure characteristics into account, the proposed energy-based (passivity-based) adaptive sliding algorithm derived from the view point of energy dissipati...

The first step in the synchronous reluctance machine design is selection of rotor flux barrier type. literature provides various construction methods with a common goal reducing parametric complexity. However, too excessive simplification can lead to decreased performance, while overly complex geometries tend increase optimization time. This paper presents set novel an increased degree freedom ...
