Since the past, social issues related to environmental issues are a problem that has been continuously contemplated worldwide, and various environmental regulations have been created and existing environmental regulations are also being strengthened. The automobile industry has also been producing products in accordance with these environmental regulations, but it is becoming increasingly difficult to match technology and production cost to produce in response to increasingly environmental regulations. For this reason, it is estimated that the speed of the transition from internal combustion engines to the era of electric vehicles is accelerating. The improvement of fuel efficiency of a vehicle is one of the important factors, and it is also an important research and development factor to develop electric and hybrid vehicles by minimizing the power loss compared to the mileage. Therefore, research on reducing the energy loss of the driving motor, which is a key component of electric vehicles and hybrid vehicles, is being actively conducted, and many manufacturers are studying motor efficiency improvement in the main use area. In this paper, the test factors related to mechanical and electrical efficiency of motors are classified, the effect of each factor on the efficiency is confirmed as the test results, and efficiency improvement is compared and analyzed. This study used a hybrid vehicle motor and inverter, and it is the result of comparative analysis of only some elements that can be changed in the test, excluding efficiency changes due to hardware changes such as a separate core or coil.
