This paper presents a power factor correction (PFC) based canonical switching cell (CSC) converter-fed brushless dc motor (BLDCM) drive for low-power household applications. The speed of BLDCM is controlled by varying the dc-bus voltage of voltage source inverter (VSI). The BLDCM is electronically commutated for reduced switching losses in VSI due to low-frequency switching. A front-end CSC con...
Cogging torque reduction of axial flux permanent magnet brushless dc (PMBLDC) motor is an important issue which demands attention of machine designers during design process. This paper presents magnet notching technique to reduce cogging torque of axial flux PMBLDC motor designed for electric vehicle application. Reference axial flux PMBLDC motor of 250 W, 150 rpm is designed with 48 stator slo...
A new permanent-magnet (PM) hybrid brushless (PMHB) machine is proposed and implemented as the integrated starter–generator (ISG) for hybrid electric vehicles (HEVs). It has the advantages of higher torque density than other PMHB machines and much wider speed range than other PM brushless machines. The key is to tune its dc-field winding current in such a way that three major modes of ISG syste...
Permanent magnet machines are very suitable for Electric vehicles and Motor pump applications because of their simple construction, ease control high efficiency. Among the different Magnet Brushless DC motors (PMBLDC) as well permanent particularly EV owing to high-speed performance constant speed-torque features. In this paper, PMBLDC motor is modelled analysed mathematically using its equival...
Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...
