Abstract: The authors argued that the innovation target of market dominating hybrid stepping motor series should be on pursuing the remarkable improvement of high dynamic performance and demonstrated that evolved development from enhanced hybrid stepping motor would be the best successor candidates. This presentation will be developing the former ideas into more detailed theoretical analysis and depicting the testing results of various engineering practice. The patented hypertorquetoothlayer structural model of hybrid stepping motor was introduced for comprehension on the increased normalization torque constant. As part of the unit product, the corresponding closed loop driving and controlling methodology was discussed as well for achieving the high dynamic system performance. In additional to the technology aspects, the improved economic benefits and cost performance of the proposed unit stepping motor system were also studied and depicted by the testing results from the production working samples with the intent of facilitating the acceptance of industries.

Key words: stepping motor; hypertorque hybrid stepping motor; market dominating series
