Permanent magnet assisted synchronous reluctance motor (PMA-SynRM) is a kind of high torque density energy conversion device widely used in modern industry. In this paper, based on the basic topology PMA-SynRM, novel PMA-SynRM asymmetric rotor with position-biased proposed. The design realizes concentration magnetic field lines air gap to obtain higher electromagnetic torque, and makes both pea...

In order to achieve improved performance and efficiency of domestic industrial fan/pump applications using low-cost solutions, the synchronous reluctance motors (SynRMs) remains a better choice than induction (IMs) which are still widely used for such despite its low during speed operation. However, due lack self-start capability SynRMs need external drive control algorithm properly operate, in...

The rare-earth (RE) permanent magnets (PM) have been increasingly adopted in traction motor application. However, the RE PM is expensive, less abundant, and has cost uncertainties due to limited market suppliers. This paper presents a new design of RE-free five-phase ferrite magnet-assisted synchronous reluctance (Fe-PMaSynRM) with external rotor architecture high saliency ratio. In such archit...

Goal. The goal of the research is to develop an algorithm for selecting main dimensions a traction permanent magnet-assisted synchronous reluctance motor. Methodology. A method determining motor, which combines analytical selection stator parameters and numerical field calculations rotor parameters. need check mechanical strength with NdFeB magnets in flux barriers shown. Results. article propo...

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...

A permanent magnet assistance synchronous reluctance motor can start directly with a net voltage or power converter via torque control method. However, this has usually higher irreversible demagnetization level in comparison interior motors, due to the fewer magnets rotor slots. In order cope disadvantage, different arrangements of line-start are proposed paper. The V shape taking skewed slots ...

in most industrial applications, including overhead cranes, two motors with equal speeds are required. to meet this, different traditional and modern methods are used. in the modern methods, work is done with more precision but the cost is remarkably high, also the maintenance of equipment needs specialized personnel. among traditional methods, the two-motors selsyn method is noteworthy due to ...

Abstract Aiming at the problem of jitter in speed when load changes abruptly during operation a synchronous reluctance motor and poor resistance to disturbance, an integral type sliding film variable structure control algorithm is proposed. The regulation controlled by mode, PI controls current regulation, Simulink simulation model system built, experiments are conducted. results show that, com...
