Design of an Innovative High-Torque Brake

Abstract:

The paper shows the design of an innovative magneto-rheological fluid brake (MRF brake). The integral brake torque from a conventional MRF brake is not quite large since it commonly adopts a single ring-type electromagnetic pole to produce magnetic flux to change the MRF viscosity. This presented innovative MRF brake features with multiple electromagnetic poles to significantly increase the active chaining areas for MRF, and then increase the brake torque. Because of the special arrangements of pole numbers and directions of magnetic flux for these poles, the active chaining areas of MR fluid and brake force are maximized. The simulation results confirmed the feasibility and ability of this innovative MRF brake. Performance comparison shows that the innovative MRF brake has 118% more torque output than a commercial one.
