Abstract
In recent years, the number of stroke patients has been increasing. The rehabilitation systems for upper limbs using force display system are expected to quantify the effect of rehabilitative training, and can enhance the motivation of an operator. A passive-type force display system uses only brake, and ensures high safety. It can display resistance force by using brake. Magneto-Rheological fluid (MRF) is one of the functional fluid and its rheological properties can be controlled by applying magnetic field. So, MRf Brake has good responsibility and high torque. In this paper, we describe development of New type MRf Brake which is cpable of generating High Torque by only one disk which is holed like a ring and its magnetic field analysis by ANSYS
