This paper describes the experimental study carried out on a Permanent Magnet Brushless DC (PMBLDC) Motor drive coupled to a pump load powered by photovoltaic (PV) array I for water pumping system. A simple low cost prototype controller has been designed and developed without current and position sensors which reduces drastically the overall cost of the drive system. This controller is used to ...

This paper describes a simpler way to control the speed of PMBLDC motor using a closed loop control method. The performance of the PMBLDC system is simulated. The speed is regulated by PI controller. SimuLink is utilized, with MATLAB to get a reliable and flexible simulation. In order to highlight the effectiveness of the speed control method used, the studies are conducted at two different loa...

This paper presents the design, analysis, and prototyping of a novel axial-flux permanent-magnet (AFPM) motor capable of auto-starting. The preliminary design is a slot-less double-sided solid-rotor line-start AFPM motor with 4 poles for high torque density and stable rotation. One spaced raised ring was added to the inner radii of the rotor disc for smooth line-start motor. The design allows t...

Digital Simulation and implementation of a Power Factor Correction (PFC) half bridge converter based adjustable speed voltage controlled VSI fed PMBLDC motor is presented in this paper. A single-phase AC-DC converter topology based on the half bridge converter is employed for PFC which ensures near unity power factor over wide speed range. The proposed speed control scheme has the concept of DC...

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 ...

The paper presents diagnostics of induction motor stator faults. The decision on stator winding condition has been taken using the axial flux and based on artificial neural network with radial basis transfer function. The axial flux has been measured for different configuration of stator winding. On the basis of research it can be concluded that the axial flux can be successfully used in detect...

In this paper, the steady-state temperature of a sample 500 KW two rotor one stator Non-slotted axial flux permanent magnet motor is calculated using the finite element simulator software package. Due to the high temperature in various parts of the machine, especially at stator winding, a cooling system is designed for the motor and the temperature is recalculated. The results show that the tem...

A new permanent magnet design for axial flux interior permanent magnet (AFIPM) motor is described in this paper. Poleshoes are traditionally used to produce sinusoidal flux linkage and sinusoidal EMF especially in the case of radial flux synchronous machines. Poleshoes are not a practical solution in the case of axial flux PM machine. The use of poleshoes in the production of sinusoidal back EM...
