Structure Design and Simulation of Viscometer Based on Velocity Attenuation
View through CrossRef
A viscometer based on velocity attenuation is presented. It is used to measure viscosity of liquid at an arbitrary velocity. Structure of the viscometer is designed. A motor designed specially called Series-Motor is used as driven motor of the viscometer to keep the flow stability of test liquid. A solid rotor motor is adapted to reduce the cogging effect. Pressure-feed air bearing is adapted as support to minimize the resistance torque. Simulation is made in MATLAB. Results show that Series-Motor reduces the resistance torque besides the viscous torque and it provides slow speed motor to keep the flow stability.
