Abstract

Abstract: In this paper, a novel bipolar transverse flux motor with stator permanent magnet excitation is proposed based on the summary and analysis of the transverse flux motor and stator permanent magnet motor research achievements in recent years. It has been shown that the motor realizes the bipolar winding flux through the detailed analysis. The motor can be used as an inwheel motor in electric vehicles because of its external rotor and permanent magnets mounted on the stator radial surface. Secondly the basic structure and working principle of the motor are introduced. Then the relationship between the motor power and its dimensions is deduced. Thirdly the 3 dimensional finite element method(3D FEM) is used to analyze the static and transient characteristics, including the no-load magnetic field distribution and winding back EMF. Finally a three-phase 600W prototype has been made and the experimental analysis is carried out.

Key words: Outer rotor, stator permanent-magnet excitation, bipolar flux, transverse flux motor
