Abstract
Interior permanent magnet (IPM) motor is one of the electric motor types. This type has been widely used in the electric vehicle as a result of its superiorities. There are many technical related studies of the IPM motor that have been done. This paper discusses the economic parameters of the IPM motor in terms of the Break-even Point (BEP), Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), with the specific purpose to estimate the product cost. The IPM motor product cost comprises direct materials, direct labor costs, tooling costs as well as operational and maintenance costs. In addition, the BEP is counted to find out the number of IPM motors that should be produced until a level where revenues equal to expenses. All computations are reckoned in Indonesian Rupiah (IDR). The calculation result of the IPM motor product cost is IDR 34,865,081.221. The value of BEP quantity is 20 units and the BEP for the revenue is IDR 93,759,338.855. The other economic parameters, which are NPV, PP, and IRR are obtained using three scenarios by assuming that the incomes of IPM motor are 0.0025 %, 0.005 %, and 0.01 % of 400 thousand electric vehicle (estimated data) or equals to 10, 20, and 40 units respectively. All of the results indicate that it is feasible for each scenario by 2025.
