| Outline of Final Research Achievements |
The purpose of this research is to realize the new variable field flux motor and brushless robust structure for wider controllable speed and higher efficiency operating range. This research accomplished the designing, control method and evaluation simulator for a novel claw pole rotor type motor using the variable field flux method (CP-HVFM).
We have studied the designing for CP-HVFM using 3D-FEM. The designed prototype CP-HVFM reached a rated power of 2kW or more at a rated speed 1800 rpm under design restrictions of experimental equipment and initial specifications. In addition, we found the best claw pole shape for maximum average torque and minimum torque ripple. We also built an experimental system using the current hysteresis controller and proposed the variable field flux control method to realize maximum torque and high efficiency characteristics. And we proposed the evaluation simulator using multi-domain simulation with motor model, inverter model, and control program model.
