© 2020, Springer Nature Switzerland AG.The problem of determining vane air motor characteristics such as torque ripple and specific air consumption (energy efficiency) is considered. Reduced torque ripple is possible due to increasing the number of vanes, but this leads to decreasing energy efficiency with increased friction losses. The solution of the problem was carried out on the basis of a detailed vane air motor mathematical model, some parameters of which were determined by the method of vector identification. Differences of calculated and experimental mechanical and flow characteristics for different pressures of air supply are taken as identification procedure criteria. This approach can significantly reduce the amount of expensive experimental work when designing air vane motors with specified parameters. This result is important to develop pneumatic precision positioning servo systems for high-frequency and magnetic resonance applications in MRT-devices and also provide ergonomic demands in pneumatic hand tools.
