RESUMO

The initial purpose of this study is to develop a methodology of analysis of the torque ripple of a two-phase special SRM 4/2 using acceleration experimental data. In order to validate the proposed method, acceleration experimental results are presented, these results were obtained with two rotors: the reference rotor and the optimized rotor. Once the torque optimization objectives were reached by modifying the rotor geometry, a complementary study from the point of view of motor drive vibration and torque ripple optimization was carried out. Thus, a test digital setup was developed, where the acceleration data could be monitored, in the frequency domain, and the drive control parameters, such as speed, turn-on and dwell angles, and phase current were flexible and could be altered by program. The test digital setup was conceived using a development kit (eZdsp LF2407A) associated with a serial control interface developed on a LabView application, installed in a microcomputer.
