Abstract This paper presents the optimal design of permanent magnet brushless DC (BLDC) motor for electromobility propulsion applications. Two BLDC machines were analyzed: (a) – exterior rotor machine, and (b) interior The optimization both motors structures was executed by Taguchi method. device structure described three variables. functional parameter (efficiency) economic (total mass magnets...

The use of a cobalt-iron (VaCoFe) core is investigated as an alternative to silicon-iron (FeSi) in the design interior permanent magnet synchronous motors (IPMSM). Considering VaCoFe and FeSi cores, spoke-type IPMSM geometry optimized for torque range up 40 N·m, providing general comparative analysis between materials. This done considering application four-motor competition vehicle’s powertrai...

permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...
