Designing a high-power controller having high efficiency for permanent magnet motors is challenge developers in recent times and very few techniques are available. Design analysis of power electronic drive axial flux synchronous motor presented this paper. The under consideration here two outer stators single rotor to the shaft. Control schemes methodologies major concentration research. Presen...

A method is proposed to comprehensively study the eddy and circulating current losses of stator winding wound by multiple parallel strands, further improve power density iron coreless permanent magnet brushless DC (PMBLDC) motors. Analytical models in are deduced firstly explicitly express influencing factors these two losses. As shown, mutually contradicting. While loss can be greatly reduced ...

This paper presents to estimating studies of the torque data Electric Vehicle (EV) motor using Adaptive-Network Based Fuzzy Inference Systems (ANFIS). The real-time set Outer-Rotor Permanent Magnet Brushless DC (ORPMBLDC) which was designed and manufactured for in ultra-light EV, used these estimation process. current, power speed parameters are defined as input variables, parameter output vari...

In this paper, a new type of harmonic injection permanent magnet shape optimization method is proposed to suppress the torque ripple surface-mounted synchronous motor. The sinusoidal waveform shaping axial section added with third shaping, and sine wave are derived. optimal ratio 6:1. no combined compared. results show that design can effectively surface mounted motor obtain relatively large ou...

Flux switching Motor (FSM) was invented in the $19^{th}$ century but started gaining importance after 2000. The simple structure and moderate cost of FSM, comparison with existing commutated Direct Current (DC) Permanent Magnet Brushl...

In a conventional three phase Brushless DC machine with 120° electrical conduction, Harmonics and commutation torque ripple occurs because of changeover of load current from one phase to another at every 60 electrical degrees. This paper presents techniques for diminishing the harmonics and torque ripples in sensor Brushless DC motor. This torque ripple reduction techniques based on voltage con...
