Application Reseach of Oriental Silicon Steel Sheet Used in the Table Motor

Abstract

The tables used in multi-axis numerical control machine need quicker response ability and higher position precision, so their drive motors must have both high torque density and low torque ripple. In order to realize these requirements, based on the characteristics of the oriental silicon steel sheet which is usually used in the transformers, a similar number of poles and slots PM (permanent magnetic) motor with this material is researched and designed. The motor stator is combined with some single tooth which rolling direction is radical. Because of the excellent magnetic performance along the rolling direction, the proposed stator structure can increase the average torque and decrease the torque ripple. In the end, the finite element soft Ansoft is used to prove that the method is correct and effective.
