  2. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

  3. Electromagnetic clutches and brakes - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_clutches...

    If a piece of copper wire was wound, around the nail and then connected to a battery, it would create an electro magnet. The magnetic field that is generated in the wire, from the current, is known as the "right hand thumb rule". (V-1) The strength of the magnetic field can be changed by changing both wire size and the amount of wire (turns).

  4. Magnetic bearing - Wikipedia

    en.wikipedia.org/wiki/Magnetic_bearing

    A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation. Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest ...

  5. Electromagnetic brake - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_brake

    Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes.

  6. Electromagnetic suspension - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_suspension

    An active magnetic bearing (AMB) works on the principle of electromagnetic suspension and consists of an electromagnet assembly, a set of power amplifiers which supply current to the electromagnets, a controller, and gap sensors with associated electronics to provide the feedback required to control the position of the rotor within the gap ...

    en.wikipedia.org/wiki/Magnetic_braking

    Magnetic braking may refer to: Magnetic braking (astronomy) , the loss of a star's angular momentum due to its magnetic field Eddy current brake , the use of magnetic induction to stop or slow a moving object

  8. Electromagnetic clutch - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_clutch

    How it works – Magnetic particles (very similar to iron filings) are located in the powder cavity. When current flows through the coil, the magnetic flux that is created tries to bind the particles together, almost like a magnetic particle slush. As the current is increased, the magnetic field builds, strengthening the binding of the particles.

  9. Electrodynamic suspension - Wikipedia

    en.wikipedia.org/wiki/Electrodynamic_suspension

    Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart. These time varying magnetic fields can be caused by relative motion between two ...
