Abstract
Serpentine flux T-shaped magneto-rheological brake (MRB) featuring a single coil has been proposed for reducing the needs of coil that usually implemented in conventional T-shape MR brake. Here, the use of serpentine type magnetic flux flow is the key to coil reduction. The prototype was designed and fabricated in the laboratory. The design covers analytical torque prediction, magnetic circuit simulation, and workshop drawing. While the fabricated prototype was characterized using MRB test rig equipped with torque and angular velocity sensors. The experimental work was carried out in constant speed and constant current. The torque using the analytical approach and experiment result respectively was 1.51 Nm and 1.91 Nm at 1 A current supplied. Based on the comparison between prediction and experiment results, it could be seen that the highest difference was about 20.
