Purpose: In this proposed work, make a electromagnetic analysis of magnetorheological brake for creating the automobile structure under the drive by wire concept. Design/methodology/approach: The proposed brake system consists of rotating disks with shaft and immersed in a MR fluid and enclosed in an electromagnet. When the current is passing through the coil wire then electromagnet is formed and magnetic field is applied. Due to the external magnetic filed, the MR fluid is converted to semi solid state and disc produced shear friction generating the braking torque. The relationship between the electric current and braking torque can be determined using electromagnetic analysis created on AutoCAD-2D model and analysed in ANSYS electromagnetics Software. In this work various types of MR fluids has been tested. Findings: In this study paper are presented at electromagnetic magnetic analysis are solved using ANSYS 15 and determined magnetic field applied on MR Brake and generating braking torque. Research limitations/implications: In an electromagnetic analysis was also carried out to magnetic distribution of the MR fluid with in brake. For various speed of rpm, when a current of 2A is applied of MRB and No. of coil 300, with the help of analytical model and magneto-static analysis the braking torque obtained.
