Cogging torque minimization in transverse flux machines
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016 This paper presents the design considerations in cogging torque minimization in two types of transverse flux machines. The machines have a double stator-single rotor configuration with flux concentrating ferrite magnets. One of the machines has pole windings across each leg of an E-Core stator. Another machine has quasi-U-shaped stator cores and a ring
