Abstract

This paper presents a design of permanent magnet synchronous motor for an agricultural utility vehicle. Based on output characteristics of conventional diesel vehicle, required speed and torque are derived and motor specification is determined. Through finite element analysis and equivalent magnetic circuit model, interior permanent magnet motor which has rated driving condition of 10kW and maximum one of 15kW is designed. In order to reduce cogging torque and increase flux linkage of motor, shape of stator core touching with air gap is analyzed. Trial product is manufactured and verifies the design validity.
