A subdomain model for armature reaction field and open-circuit field prediction in consequent pole permanent magnet machines
Abbas, Ahmed; Iqbal, Atif ( John Wiley and Sons Ltd , 2022 , Article)In this paper, the machine quantity, such as electromagnetic torque, self and mutual inductances, and electromotive force, is analytically calculated for non-overlapping winding consequent pole slotted machine for open-circuit ... -
Investigation of the Effect of The Temperature and Magnetization Pattern on Flux Density, Instantaneous Torque, Unbalanced Magnetic Forces of a Surface Inset PMM
Abbas, Ahmed; Iqbal, Atif; Hosseinpour, A.; Shahabuddin, Mohammad; Kabalci, Ersan ( Institute of Electrical and Electronics Engineers Inc. , 2022 , Conference Paper)Electrical machines utilized in domestic applications such as ceiling fans should have low losses and cost. Permanent magnets are used instead of rotor excitation to reduce losses. Therefore, not only the losses of the ... -
