권선방식에 따른 센서리스 구동용 동기전동기 설계

Abstract

This paper design a motors well adapted to position sensorless control method based on the high frequency signal injection and proposes a direction to design for sensorless control in interior permanent magnet synchronous motor(IPMSM) as a type of winding. In sensorless control, controller calculates the position of rotor at smallest d-axis inductance from high frequency injection. In order to satisfy this characteristic, this paper designs a motor as a type of winding. Distributed winding is good for sensorless control, because it has low saturation in iron core and better flux distribution than concentrated winding’s. Inductance is calculated by the FEM using frozen permeability method and voltage equations of d-q axis are used to analyze characteristics of IPMSM such as torque, output power, current angle and efficiency.
