Avanepneumatic motor modification to reduce torque ripples

Annotation The problem of determining and possible ways to reduce the amplitude of torque ripples in a vane pneumatic motor without a significant reduction of its energy efficiency is considered. This problem is important for improving the ergonomic performance of manual mechanized pneumatic tools and improving the accuracy of pneumatic servosystems. The results are presented for the traditional layout scheme of a vane pneumatic motor, as well as for the proposed modified design. The decision was made using a detailed mathematical model of a pneumatic motor. The prospects of the modified pneumatic motor to reduce the torque ripples at higher energy efficiency indicators are shown, compared with the original model with an increased number of vanes.
