i hope which is already topicideashow-to-Electromagnetic-brakes

wait some others may here...your pain
see en.wikipediawiki/Electromagnetic_brake

Friction between contact surfaces leads to generation of
heat that causes temperature increase of components.
(consequences- fading and disk warping)
Wear and tear of friction lining
during braking.
Less accuracy of applied braking
Performance reduction is more
with passage of time.
Require more maintenance.
Take large space and have greater
It becomes self locking if properly not designed.
The brake imposes controlled deceleration at variable speeds.
Braking system having smooth response, thereby eliminating shock loading and extending equipment life.
No physical contact between rotating and stationary members.
Produce required braking torque within given constraints and parameters
To demonstrate the production of torque, we will essentially take the driveshaft and build a test rig around it.  By attaching a conductive disc to the driveshaft and setting up electromagnets around it, we can create a braking force (assuming the disc is moving fast) to decelerate the driveshaft.  If we can prove that the required torque is achievable via eddy-current-braking, then the electro-magnets can be installed.
FARADAY’S LAW : The induced electromotive force(emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit.
AMPERE CIRCUITAL LAW : It relates the integrated magnetic field around a closed loop to the electric current passing through the loop.
LORENTZ FORCE: It is the force on a point charge due to electromagnetic fields. F= I (L X B)
LENZ’S LAW : An induced current is always in such a direction as to oppose the motion or change causing it.
FUNDAMENTAL physics of eddy-current braking
Conductor moves across a magnetic field(Electromagnet)
Electric field will be produced due to time varying magnetic flux
Eddy currents generated due to electric field
These currents exert an opposing force on conductor
Eddy Current Brake Rationale
Non-mechanical (no moving parts, no friction)
Contactless braking and absence of maintenance
Fully resettable, no parts need be replaced
Can be activated at will via electrical signal
Operates at any rotational speed
Reduced sensitivity to high temperatures
Relative ease of control
Requirement for a large excitation current
Lack of failure safety
The excitation current is necessarily supplied at a low voltage, which induces high ohmic losses in conductors, diminished bus voltage, and renders electronic control challenging.
Heavy wiring from the battery to the retarder, heating of the coils
Motor characteristics:
Nominal armature voltage 180 V
Nominal armature current 14 A
Armature resistance 1.43 Ω
Maximum speed 1440 rpm
Nominal shaft power 1 hp
Maximum torque 4.94 N.m
Torque constant 0..352 N.m/A
electromagnet residual flux density Br 0.4 T
Reluctance of core and air gap L 3.22x10e7 AT/Wb
Magnetic flux intensity ø 0.0133 milliweber
Electromotive force required MMF 430 AT
Number of turns of coils N 145
Current applied to electromagnet I 3 A
