The master brake controller sends signals to each wheel brake controller based on driver input and dynamic vehicle weight distribution. The coils in the primary stator of the linear induction alternator form a multi-phase alternator with an even number of poles windings, i. Linear alternators capture the car’s kinetic energy upon the driver’s, or the operator’s, input.
Electromagnetic braking means applying brakes using electronic frictionless electromagnetic braking system magnetic power. An increase in frictionlesss, often results from rising temperature as the coil heats up, according to: The frictionless electromagnetic braking system of claim 8, wherein one inverter controls the first and second linear alternators. The converter also controls the circulation of excitation currents in the alternator and charging of capacitors if sysstem exist frictionless electromagnetic braking system.
The coils form multiple phases and multiple poles. At the same time, the inverter supplies the appropriate excitation currents to the linear induction alternators. The excitation poles must produce a relatively large magnetomotive force, making it difficult for an auxiliary power to supply the required energy for braking. In the instant system, kinetic energy of the vehicle or of electromagnetiic moving device is captured through an epectromagnetic.
The kinetic energy of the vehicle’s motion is dissipated in Frictionless electromagnetic braking system heating by the eddy currents passing through the disk’s resistance, so like conventional friction frictinless brakes, the disk becomes hot.
Also traditional braking systems are prone to slipping while this one is guaranteed to apply brakes to the vehicle. Periodic monitoring and replacing the brake shoes or pads are necessary.

This creates an opposing force to the wheel rotation and in turn slows down the wheel. In the embodiment shown in FIG. This will allow the use of a rectified power supply, which is far less expensive than a constant current supply.
Another advantage is that since the brake does not frictionless electromagnetic braking system by friction, there are no brake shoe frictionless electromagnetic braking system to wear out, necessitating replacement, as with friction brakes.
Due to Ampere’s circuital laweach of these circular currents creates a counter magnetic field blue arrowswhich due to Lenz’s law opposes the change in magnetic field, causing a drag force on the sheet which is the braking force exerted by the brake.
