2. 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 ...

3. 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 ...

4. Electromagnetic clutches and brakes - Wikipedia

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

   Bushings can be used in some clutches that have low speed, low side loads or low operating hours. At higher loads and speeds, bearing mounted field/rotors and hubs are a better option. Most brakes are flanged mounted and have bearings but some brakes are bearing mounted.

5. Eddy current - Wikipedia

   en.wikipedia.org/wiki/Eddy_current

   One is in the brakes of some trains known as eddy current brakes. During braking, the metal wheels are exposed to a magnetic field from an electromagnet, generating eddy currents in the wheels. This eddy current is formed by the movement of the wheels. So, by Lenz's law, the magnetic field formed by the eddy current will oppose its cause. Thus ...

6. Magnetic gear - Wikipedia

   en.wikipedia.org/wiki/Magnetic_Gear

   An intermediate ferromagnetic pole "stator" is usually held stationary between the rings, to direct the concentration of the magnetic lines between the high speed rotor and the low speed rotor. The gear ratio between the rotors is the number of magnetic pole pairs on the high speed rotor to the number of magnetic pole pairs on the low speed rotor.

7. 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 ...
