Development of a new magnetorheological fluid–based brake with multiple coils placed on the side housings

In this research, a new configuration of magnetorheological fluid–based brake with multiple coils placed on each side of the brake housing (multiple side-coil magnetorheological fluid–based brake) is proposed, optimally designed, and evaluated. With this configuration, the multiple side-coil magnetorheological fluid–based brake is expected to provide higher braking torque and more compact size than the traditional magnetorheological fluid–based brake. After a brief introduction about the development of magnetorheological fluid–based brake, the configuration of multiple side-coil magnetorheological fluid–based brake is proposed. Braking torque of the proposed magnetorheological fluid–based brake is then analyzed based on the Bingham plastic rheological model of magnetorheological fluid. The optimization of the proposed multiple side-coil magnetorheological fluid–based brake, the magnetorheological fluid–based brake with one coil placed on each side of the brake housing (single side-coil magnetorheological ...
