Effect of Magnetorheological Grease’s Viscosity to the Torque Performance in Magnetorheological Brake [PDF]
Materials, 2022 Recently, magnetorheological grease (MRG) has been utilized in magnetorheological (MR) brakes to generate a braking torque based on the current applied. However, the high initial viscosity of MRG has increased the off-state torque that led to the viscous drag of the brake.

Torque Enhancement for a New Magnetorheological Brake
Procedia Engineering, 2014 AbstractThe conventional magnetorheological fluid (MR) brake has been used as resistant sources for specific applications. However, the limited torque prevents it to be widely commercialized. This paper presents a new MR brake that improves the brake torque by enlarging the magnetic field strength.
