Design and analysis of an MR rotary brake for self-regulating braking torques

Review of Scientific Instruments, 2017
This paper presents a novel Magneto-rheological (MR) brake system that can self-regulate the output braking torques. The proposed MR brake can generate a braking torque at a critical rotation speed without an external power source, sensors, or controllers, making it a simple and cost-effective device.

Effect of disc hardness on MR brake performance

Engineering Failure Analysis, 2017
Abstract The online control of frictional force using MR fluid makes Magneto-Rheological (MR) brake an attractive option to replace the conventional disc brake. However, initial experiments on MR brake showed deterioration in the braking performance with time.

Computer Controlled Rotational MR-brake for Wrist Rehabilitation Device

Journal of Intelligent Material Systems and Structures, 2010
This aricle presents a novel, computer controlled, magneto-rheological (MR) brake actuated, muscular rehabilitation, and evaluation device. The first part discusses various MR brake architectures and compares them. Simple analytical formulae are developed for a set of figures of merit, which point out the role played by the various parameters. Based on

Mr-brake with permanent magnet as passive actuator for haptics

2013 World Haptics Conference (WHC), 2013
In haptics applications, fast, stable and crisp force responses are desired. Magnetorheological (MR) brakes are viable actuators for haptics since they provide high torque-to-volume ratios with fast response. However, they tend to be rather large and use high current inputs.

Design of a Novel MR Rotary Brake

2009 WRI World Congress on Computer Science and Information Engineering, 2009
In this paper, a novel MR (magneto Rheology)rotary brake is introduced. A conventional MR brake is equipped with coil, drive and power supply, so,external current should be applied into the coils. But the proposed system has its own generator, so no external current source is not needed.

Pneumatic actuator with embedded MR-brake for haptics

2017 IEEE World Haptics Conference (WHC), 2017
A pneumatic cylinder with an embedded magnetorheological (MR) brake has been developed. The new hybrid actuator benefits from the advantages of MR-brakes and pneumatic cylinders. It can apply forces using compressed air and can resist external forces using the MR-brake.

Energy-saving control of an unstable valve with a MR brake

Proceedings of the 2005, American Control Conference, 2005., 2005
In fluid power systems, excessive heat often causes solenoid failure. Heat, as well as useful power of a solenoid, is associated with the current. In this paper, we attempt to alleviate the requirement for the solenoid power, thus reducing the heat generation accordingly.
