Interior
permanent magnet synchronous motors (IPMSMs) are widely used in electric
vehicles (EVs) due to their electrical and mechanical characteristics. In
addition to the magnetic torque generated by the magnets in the IPMSM motors, a
higher torque density is achieved by generating reluctance torque resulting
from the inductance variation of the rotor on the d-q axes. Therefore, rotor and
magnet geometry have significant effects on the motor performance. In an IPM
design, it is often desirable to have maximum torque and flux weakening
capability, minimum torque ripple, and low rotor harmonic losses. For this
reason, rotor geometry is the most important part that affects the overall
performance of the motor. In this study, a 100kW, single layer design V-shape
structure IPMSM has been designed. The motor is optimized by considering
important geometric data such as rotor geometry, magnet dimensions, bridge and
flux barrier. Thus, it is aimed to design an optimum IPM traction motor
considering efficiency and cost criteria. Also, the study provides design
criteria that can meet low leakage flux and low cogging torque requirements for
rotor topologies with V-shaped structures. 2D finite element analyzes have been
used to verify the theoretically optimized designs.
