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. 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.

5. Electromagnetic clutches and brakes - Wikipedia

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

   Similarly, two-piece brakes that have separate armatures should be burnished on a machine rather than a bench because any change in the mounting tolerance as that brake is mounted to the machine may shift the alignment so the burnishing lines on the armature, rotor or brake face may be off, slightly preventing that brake from achieving full torque.

6. 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.

7. Squirrel-cage rotor - Wikipedia

   en.wikipedia.org/wiki/Squirrel-cage_rotor

   The shape and depth of the rotor bars can be used to vary the speed-torque characteristics of the induction motor. At standstill, the revolving magnetic field passes the rotor bars at a high rate, inducing line-frequency current into the rotor bars. Due to the skin effect, the induced current tends to flow at the outer edge of the winding.
