N2 - This research proposes a design method to reduce shaft voltage of the propulsion motors based on the motor configuration considering electromagnetic performances. First, design variables that affect parasitic capacitance are investigated by FEM. Many articles have been submitted, in which they used the insulated rotor, ceramic bearing, and ground ring. However, since the methods require manufacturing costs, it is not effective to mitigate the shaft voltage. In addition, electro-magnetic performances according to the variables are analyzed by FEM. As a result, Lcr is the most significant variable to decrease the shaft voltage. optimization for reduction of the shaft voltage considering the electromagnetic charateristisc is performed. As a result, the shaft voltage of the optimization model has 22.52 % lesser shaft voltage maintaining the electromagnetic characteristics.
