Analysis of a Novel Transverse-flux Machine with Dual-tooth-slot Core Configuration for Direct-drive Applications

In this paper, a novel transverse-flux machine with dual-tooth-slot core configuration is proposed for direct-drive applications, which is characterized by high-torque density and high utilization rate of motor space. Firstly, the structure and working principle of proposed machine is introduced. Then, the basic electromagnetic performance is analyzed by finite-element method. Then, some influences of design dimensions on electromagnetic torque and cogging torque are analyzed. The torque density per volume of proposed motor is 20.2kN.m/m
³
(force density per gap area is 2.3N/mm
²
), which is considerable excellent among various transverse flux motors.
