Modeling of Iron Losses of Permanent-Magnet Synchronous Motors
Permanent-magnet (PM) motors offer potential energy savings as compared with induction motors because of the virtual elimination of rotor loss and the reduction of stator loss from operation near unity power factor. In PM machines, iron losses form a significant fraction of the total loss partly due to the nonsinusoidal flux density distribution. Design optimization therefore requires good mean...
متن کاملAnalytical Calculation of Magnetic Field Distribution and Stator Iron Losses for Surface-Mounted Permanent Magnet Synchronous Machines
Permanent-magnet synchronous machines (PMSMs) are widely used in electric vehicles owing to many advantages, such as high power density, high efficiency, etc. Iron losses can account for a significant component of the total loss in permanent-magnet (PM) machines. Consequently, these losses should be carefully considered during the PMSM design. In this paper, an analytical calculation method has...
متن کاملIron Loss Prediction Using Modified IEM-Formula during the Field Weakening for Permanent Magnet Synchronous Machines
During field weakening operation time (FWOT), the total iron loss rises and affects the accuracy of loss prediction and efficiency, especially if a large range of FWOT exists due to a large voltage drop that was rooted from the resistance of the used material. Iron loss prediction is widely employed in investigations for a fast electrical machine analysis using 2D finite element analysis (FEA)....
متن کاملInfluence of stator slot openings on losses and torque in axial flux permanent magnet machines
Among the different geometrical parameters to be chosen during design of axial flux permanent magnet synchronous machines, the width of the stator slot openings near the air gap is an important parameter: it has a major influence on the power loss in the stator core and in the permanent magnets on the two rotors of the studied type of axial flux machines. Moreover, the stator slot openings para...
متن کاملRotor Losses in Axial-flux Permanent-magnet Machines with Non-overlapped Windings
A characterization of the rotor losses in single-sided axialflux permanent-magnet (AFPM) machines fitted with nonoverlapped windings (NOW) is presented in this paper, through experimental validation of finite element analysis (FEA) estimates. A literature review detailing the previous work done in the area of rotor loss estimation is given and the approaches taken by the authors to model the AF...
