| Popis: | In this paper, the shape design of the T-flange type MR brake for weight reduction is studied theoretically. And the small lightweight MR brake shape design with an intuitive structure having high output torque is proposed. The equations for transmitted torque are derived according to T-flange configurations of the MR brake. The validity of the theoretical results is verified by the analyses of an electromagnet using the finite element method. The magnetic flux density is evenly distributed in the T-flange type MR brake. Then the effectiveness of the propsoed MR brake braking torque is verified to reinforce by comparing the output torque of the disk type MR brake through the experiment. The output torque performance is exhibited in 2.2 times as compared to the disk type MR brake. |
