Load Rotational Moment and Power of Centrifuges with Rotational Arms
The load rotational moment and power of a centrifuge with rotational arms (CWRA) consist of aerodynamic, inertial and frictional rotational moments and related powers, respectively. The chosen electromotor based on previous calculations cannot accurately provide proper moment and power for dynamic CWRAs. In this paper, the maximum load rotational moment and maximum load power of a CWRA were formulated, a method to calculate the rating power of its driving electromotor was suggested, and an analytical computational example was performed. The results show that the present method is much more accurate than previous ones.
