Abstract
The paper presents the results of magnetic field and braking torque using Magnetorheological Fluid (MRF). A Magnetorheological Brake (MRB) was designed, simulated and calculated the generated braking torque. The MR brake model consists of: two rotors, a stator with six upper winding and two MRF layers between the rotors and stator. From the 3D model, a 3D finite element electromagnetic model of MRB was built and simulated by FLUX software. From the results of the magnetic field strength, the magnetic flux density will calculate the braking torque based on the Bingham Rheological model of MRF. Summary, this study simulated the magnetic field of the MR Brake and calculated the braking torque for different MRFs.
