• Noted the disadvantages of frictional braking system
• Selected Motor and designed the pulleys and belt for power transmission.
• Designed the bearings, hub, bearing support, shaft and key
• Calculated the magnetic induction produced by the magnets and the braking torque generated on the aluminum disk.
• Applied the concepts of electromagnetism (eddy currents) for the application of brakes.
• Designed a 3D model of the prototype on SolidWorks & performed structural analysis of shaft in Ansys for fatigue failure.
• Designed a clamping-lever mechanism that could hold the magnets and pivot to apply brakes.
• Used aluminum rotor disc and C30 steel shaft due to their favorable properties. Used Neodymium magnets instead of electromagnets which saved 20% of the project cost and reduced brake time by 2 seconds
