Published by The Mattingley Publishing Co, Inc. Fig. 3. Axial View of BLDC Motor The simulation workflow is a pattern of various selections, judgements, trials and errors. The simulation is started by choosing any default (basic) design or by uploading a design of the user’s choice. Once the design
and type of motor is selected, the user is taken through an interactive environment where there are many options towards the type of motor the user would like to develop. This feature is unique and allows fora very malleable simulation workflow. The simulation workflow is shown as follows. Note that this workflow is followed for the
Stator and Rotor individually.
1) Mechanical Dimensions Initially the user is determined to set in the mechanical dimensions such as the Inner and Outer Diameter of the core,
the length of the core, and number of slots, slot depth, slot height and various other mechanical parameters. Note that these parameters do make a large impact on the simulation output. Parameters
such a number of poles, pole pitch as such also play a key role in the simulation environment. As for the example in the article, the important parameters are enclosed within the Table II.
2) Material Selection In this section, the materials for the stator and rotor are chosen. The
type of material used for each, the stator and rotor determine the weight of the motor. The weight of the motor is a very major aspect for Electrical vehicles as the heavier the motor is, the battery density is exponential and hence calls fora very bulky system. For the current example, the stator material is selected
as Bakelite due to low density, high temperature resistance and reasonable mass. For the efficiency of the motor to stay intact, the type of magnet used as the magnetic core bars are
