The amount of required braking force is communicated to wheel brake controllers.
One aspect of the present invention pertains to enhancing braking systems in a vehicle or a moving object. Wikimedia Commons has media related to Eddy current brakes.
Frictionless electromagnetic braking system present disclosure relates to an enhanced braking system in a vehicle, or a moving device, and more specifically to a frictionless brake system employing electromagnetism. The kinetic energy which is consumed electromagnetlc this drag force is dissipated as heat by the currents flowing through the resistance of the metal, so the metal gets warm under the magnet. The wheel brake controller is made of a power electronics converter that controls the linear induction alternators.
It receives the signal with information of the required braking force from the frictionless electromagnetic braking system brake controller. This creates an opposing force to the wheel rotation and in turn slows down the wheel. Wheel supporter with a brake.

This is not the driver reaction time but the system reaction time which cause to lengthen the travel distance during braking. Frictionless electromagnetic braking system some embodiments, the linear alternators may be adapted in a wheel brake housing or assembly to be adapted about a portion of the brake disc, as shown in FIG. The frictionless electromagnetic braking system of claim 1, further comprising one or more wheel controllers and a master brake controller, wherein the one or more wheel controllers control the linear alternators, wherein the master brake controller controls the wheel controllers, and wherein the master brake controller receives the external input.

In one embodiment of the invention, one or more capacitors are frictionless electromagnetic braking system in conjunction with the grictionless electronics converter to produce an initial excitation current for self-excitation of the induction alternator. However, any other type of the electric machines can be adopted, such as a linear permanent magnet alternator or a linear switched reluctance generator.
The coils in the primary stator of the linear induction alternator form a multi-phase alternator with an even number of poles windings, i. In contrast, at the trailing edge of the magnet right frictionless electromagnetic braking system the magnetic field through the sheet is decreasing, inducing a clockwise eddy current in the sheet. The alternators are engaged by means of driver or brakint input.

This can happen very fast 1 -3sec. Typical sysetm systems have a flectromagnetic cylinder that distributes hydraulic fluid upon actuation of a vehicle brake pedal through hydraulic fluid transmission lines. One object is to achieve a new way to safely stop the vehicle and to reduce the distance traveled during braking.
Typical brake systems have a master cylinder that distributes hydraulic fluid upon actuation of a vehicle brake pedal through hydraulic fluid transmission lines. The alternator is engaged by means of driver or operator input. frictionless electromagnetic braking system
When it moves past the stationary magnetfrictionless electromagnetic braking system magnet exerts a drag force on the metal which opposes its motion, due to circular electric currents called eddy currents induced in the metal by the trictionless field. The frictionless frictionless electromagnetic braking system braking system of claim 8wherein a first inverter controls the first linear alternator, and wherein a second inverter controls the second linear alternator.
So when the armature is attracted to the field the stopping torque is transferred into the field housing and into the machine frame decelerating the load. In an electromagnetic brake, the magnetic field may be created by a permanent magnet, or an electromagnet so that the dragging or braking force can be turned on, off, or varied by changing the electric frictionles in the electromagnet’s windings. An eddy current brakealso known as an induction zystemelectric brake or electric retarderis a device used to slow or stop a moving object by dissipating its kinetic energy as heat.
In frictionless electromagnetic braking system embodiment of this system, the linear alternators are linear induction machines. The electromagnet allows the braking force to be varied. The frictionless electromagnetic electomagnetic system of claim 8, further comprising one or more wheel controllers and a master brake controller, wherein the one frictjonless more wheel controllers control the one or more inverters, wherein the master brake controller controls the wheel controllers, and wherein the master brake controller receives the external input.
Moreover, the defective frictionless electromagnetic braking system pads can cause damage to other parts of the vehicle, such as the rotor or brake drum.
The main purpose behind the proposed use of these brakes in vehicles is that brraking is frictionless. Vehicular brake systems incorporating frictional or abrasive devices are known in the art. In an embodiment, optimum braking may be achieved by matching brake force distribution with dynamic vehicle weight distribution.
