The transient and dynamic performance analysis of a proposed line-start, three-phase concentrated dual-winding synchronous reluctance motor (cDWSynRM) in comparison with the conventional winding (cSynRM) was presented. Both windings are overlapping windings. cDWSynRM consist main auxiliary capacitive assistance for power factor improvement. modelling motors (SynRM) done direct-phase variables c...

Simulation studies of three synchronous reluctance motor (SynRM) control strategies are presented: field-oriented (FOC), direct torque (DTC), and finite-set model-predictive (FS-MPC). FOC uses linear controllers pulse-width modulation to the fundamental components load voltages vectors. In contrast, DTC FS-MPC nonlinear wherein voltage vectors directly generated in absence a modulator. Theoreti...

In this paper, internal division point genetic algorithm (IDP-GA) was proposed to lessen the computational burden of multi-variable multi-objective optimization problem using finite element analysis such as optimal design electric bicycles. The IDP-GA could consider various objectives with normalized weighted sum method and reduce number function calls novel crossover strategy vector-based patt...

In this paper, a discrete skew methodology is presented to understand the effect of skewing angle on electromagnetic torque in SynRM design. A new approach proposed estimate amplitude each ripple component as function angle. The reduction factor for harmonic derived general form, allowing determination overall waveform. validity method evaluated through examination two SynRMs, resulting up 70%....

Fault diagnosis techniques applied to synchronous motors such as Permanent Magnet Synchronous Machines (PMSMs) and Reluctance (SynRMs) are scarcely addressed in the literature, strong contrast attention paid asynchronous motors. In addition, most widespread those based on steady-state condition analysis, little is detection during transient operation. The present paper aims identify research ga...

This paper compares four prototype Synchronous Reluctance Motors (SynRMs) having an identical geometry of iron lamination stacks in the stator and rotor. Two different stator winding layouts are employed: a conventional three-phase star connection and a combined star–delta winding. In addition, two rotors are considered: a conventional rotor without magnets and a rotor with ferrite magnets. The...

This paper proposes a method that combines random forest technology (RF) and genetic algorithm (GA) for optimal design of traction motors electric vehicles (EVs). The target motor is permanent magnet assisted synchronous reluctance (PMa-SynRM), which the goal to increase average torque efficiency while reducing total harmonic distortion (THD) line-to-line back electromotive force (LtoL BEMF) ri...

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...

Based on the complex structural characteristics of permanent magnet-assisted synchronous reluctance motors (PMA-SynRMs), this paper proposes a multi-objective optimization design method for motor using composite algorithm. Firstly, power density, electromagnetic torque, cogging and torque fluctuation coefficient were used as targets based parametric analysis data 14 structure variables, where s...
