The search for replacement of commutator and brushes in conventional DC motors by electronic commutator has resulted in a class of Permanent Magnet Brush Less (PMBL) motors. The operation of PMBL motor requires synchronization of coil currents with the instantaneous rotor position. The applied voltages of higher magnitudes must have same zero crossings as that of speed induced back EMF of the r...

ermanent Magnet Brushless DC Motor (PMBLDC) is one of the best electrical drives that have increasing popularity, due to their high efficiency, reliability, good dynamic response and very low maintenance. Due to the increasing demand for compact & reliable motors and the evolution of low cost power semiconductor switches and permanent magnet (PM) materials, brushless DC motors become popular in...

The purpose of this paper is the calculation of Unbalanced Magnetic Force (UMF) in permanent magnet brushless DC (PMBLDC) machines with diametrically asymmetric winding and investigation of UMF variations in the presence of phase advance angle. This paper presents an analytical model of UMF in surface mounted PMBLDC machines that have a fractional ratio of slot number to pole number. This model...

Permanent-magnet brushless dc motor (PMBLDCM) is more suitable for electric vehicle (EV) with higher torque and driving performance. A loss modeling of PMBLDCM proper analysis can improve the control stability at different road surface conditions. However, iron not minimal enough to be ignored during high-speed operation drives. This article proposes a disturbance observer-based sensorless driv...

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...
