Abstract

This paper investigates the dq current trajectory for maximum torque per ampere(MTPA) operation of an interior PM synchronous motor for HEV(Hybrid Electric Vehicle). Based on the dq current trajectory for the MTPA operation derived from the motor parameters, the change of the MTPA operating point for the variation of the motor parameters including the magnet flux and the dq inductances is considered. The dq current trajectory for MTPA operation is verified through the experiment.

본 논문에서는 HEV용 영구자석 매립형 동기전동기의 단위전류 당 최대토크 운전을 위한 dq 전류 궤적에 대하여 고찰하였다. 전동기 상수로부터의 단위전류 당 최대토크 운전을 위한 dq 전류를 해석하고, 이를 바탕으로 영구자석의 자속 및 dq 인덕턴스 등의 전동기 상수가 변할 경우 단위전류 당 최대토크 운전점의 변화를 고찰하였다. 또한 단위전류 당 최대토크 제어를 위한 dq 전류의 궤적을 실험을 통하여 검증하였다.
