Abstract

The
purpose of this study is to optimize the package geometry in wheel motors for
an electric vehicle. In this context, it is aimed to analyze and design
in-wheel asynchronous motor with a conical geometry for an electric vehicle.
Thus, an asynchronous motor with a conical geometry and in-wheel asynchronous
motor with a radial flux have been evaluated by comparing performance against
each other within the package boundaries. An asynchronous motor design for the
required performance requirements was realized by using the Ansys RMXprt
program. The package analysis for the designed asynchronous motor was performed
and the minimum and maximum package sizes for in-wheel asynchronous motor. The
motor with conical geometry which is designed as a tapered geometry in 3D
according to the minimum and maximum dimensions. In the Ansys Maxwell program, these
3 type motors were analyzed in terms of the rated torque, the rated revolution,
the starting torque, the breakdown torque, the power factor, the efficiency and
the magnetic flux on the rotor and the stator. It has been seen that every
motor has advantages and disadvantages in the study. In this context, an
asynchronous motor with a conical geometry may provide optimization for the
desired properties.
