Magnetic bearing - Wikipedia

An active magnetic bearing works on the principle of electromagnetic suspension based on the induction of eddy currents in a rotating conductor.When an electrically conducting material is moving in a magnetic field, a current will be generated in the material that counters the change in the magnetic field (known as Lenz's Law).This generates a current that will result in a magnetic field that ...

Field flow fractionation - Wikipedia

Field-flow fractionation, abbreviated FFF, is a separation technique which does not have a stationary phase.It is similar to liquid chromatography as it works on dilute solutions or suspensions of the solute. Separation is achieved by applying a field (hydraulic, centrifugal, thermal, electric, magnetic, gravitational, ...) perpendicular to the direction of transport of the sample which is ...

Magnetic coupling | KSB

A magnetic coupling can be used to transfer power to centrifugal pumps. It consists of a primary part which is rigidly connected to the motor shaft, and a secondary part which is arranged on a shaft (see Pump shaft) together with the impeller. Both the primary and the secondary parts are fitted with permanent magnets. Poles of opposite polarity face each other. They attract each other due to ...

Design of High-Speed Magnetic Centrifugal Blower Impeller ...

Currently, most domestic blower speed is still in 3000r/min level. The friction loss of mechanical bearings results in their low efficiency. To further improve the efficiency of the fan, a new high-speed maglev centrifugal fan was developed specially. The design of impeller styles, structure and size are rational. 3D graphics of the impeller and volute were drawn by using solidworks software.

Electromagnetic Clutch - EMWorks

When the magnetic field exceeds the air gap between rotor and armature and then it pulls the armature toward the rotor. The frictional force generated at the contact surface transfer the torque. Engagement time depends on the strength of magnetic fields, inertia, and air gap. When voltage is removed from the coil, the contact is gone.
