Research of IPM electrical machine with flux barriers

The paper presents an electrical machine prototype with embedded permanent magnets and magnetic barriers for electric motorcycle drive. The selected experimental results in comparison with simulation results carried out by using Ansys Maxwell have also been presented. Individual stages of design and construction of the proposed machine have been reported. The aim of the work was to build and test the electrical machine with permanent magnet dedicated to the electric vehicle drive. The machine should have a high ratio of inductances in the q-axis to the d-axis, low values of cogging torque and low torque ripple. On the basis of simulation study, carried out for different topologies, the selection of rotor structure with the favorite magnetic parameters has been done. The prototype machine was built based on the stator and housing of commercial 6.3 kW induction motor.
