Abstract—
This working paper presents a design of the switched reluctance motor (SRM) for the electric scooter using the coefficient method. Experienced designers usually design an electric motor by analytical or magnetic field analysis. Difficulties arise for those who lacked experience in designing reluctance motor. So this working paper aims to produce guidelines to construct a switched reluctance motor. In this working paper, switched reluctance motor is modelled using coefficient method developed as a quick reference in determining the geometry of SRM based on past research. Next, the designed model would be analyzed using ANSYS Maxwell finite elements software. Simulation of the said model is in the Maxwell two dimensions with standard external circuit excitation with different switching angles. The expected outcome can be observed from the effects of switching angle on torque and current winding profile. As a result, the effect of switching is identified.

CONCLUSION
The coefficient method successfully applied as preliminary guidelines on SRM construction. Later, it had to be strengthened with another designed tool to enhance the output performance. The optimization stage is performed in order to achieve the desired performance on the topic, however, the lack of accuracy and aspects on effects of saturation is not included. Regarding the effects on switching mode, it can be concluded that, to generate positive output torque, voltage pulses must be injected accurately while rotor position and stator position starts to align. Otherwise, the negative torque is produced.
