This document describes an electromagnetic braking system designed for physically challenged people. It notes several challenges with conventional hand-operated braking systems, including less brake force and efficiency. The proposed electromagnetic braking system would provide better portability and comfort for drivers while having simpler operation, less chance of failure, and better compactness compared to conventional systems. It works based on Lenz's law and Faraday's law of induction, using electromagnets to generate braking force electronically rather than through brake fluid. The system could allow for faster and more flexible braking, especially in electric vehicles, with advantages like being frictionless, generating less heat, and requiring less maintenance than traditional brakes.

2. CONVENTIONAL BRAKING SYSTEM
• Brake fluid leakage
• Frequent replacement of brake pad
• Heating issues leading to brake fading
• Less efficiency of braking when engine is off
• Requires more maintenance

3. CHALLENGES FOR CONVENTIONAL HAND
OPERATED BRAKING
• Hand operated brakes –less brake force
• Less braking efficiency
• For brake operation hand should be taken from the steering
wheel

4. NEED OF ELECTROMAGNETIC BRAKING
SYSTEM
• Better portability
• Improved comfort level of the physically
handicapped (driver)
• Simple operated mechanism
• Lesser chances for failure
• Better compactness

5. PRINCIPLE
Lenz’s Law
An induced electromotive
force (emf) always gives rise to a
current whose magnetic field
opposes the change in orignal
magentic flux.
Faraday’s Law of Induction

12. ELECTROMAGNETIC BRAKING WITH ABS
• Replace the brake fluid lines by wire
• Microprocessor or control module is used
to control the current flow to each wheel
• Faster operation is possible
• More flexible to implement in EV and autonomous vehicles
12

13. ADVANTAGES
• Friction-less
• Less heat loss
• Fully electronically controlled
• Great braking efficiency
• No need of brake fluid
• Less maintenance cost
• Longer life span compared to conventional brakes
13
DISADVANTAGES
• Brake system drains
down the battery much
faster
• Residual magnetism

14. PRESENT APPLICATIONS
• High speed electric trains
• Ride and roller coasters
• Electromagnetic brakes can be incorporated
in heavy vehicles as an auxiliary brake
• Servo motors and robotics
• Elevators and escalators
14

15. CONCLUSION
• The electromagnetic braking operation is faster, safer and effective than
conventional braking system.
• We can implement this with ABS for better operation also compactness
(avoiding the brake fluid lines).
• Eliminate the issues of conventional brakes like drum ovality, over heating,
brake pad replacement, brake fluid leakage, brake drum cleaning etc.
