Abstract

Technology of attaching electric drive motors directly to wheels has become
one of the trends in electric vehicle drive systems. This article presents the design
and simulation of an external brushless dc (BLDC) motor. First, the material
parameters, stator size and rotor are selected and calculated according to the
traditional method. Software tools, ANSYS RMxprt, are used to build engine
geometry and to calculate basic design parameters. Then, set up a twodimensional element model using ANSYS Maxwell. The magnetic and torque
characteristics of the model were analyzed. The results show that the engine
design is reasonable.
