Webb16 aug. 2024 · Due to time variations in the magnetic flux, eddy currents (ECs) that surround the magnetic flux lines are inducing a conduction medium, leading in electrical machines to undesirable iron loss and a reduced efficiency [1,2,3].They are, however, vital to the action of a magnetic braking system such as an eddy current brake (ECB) where …

Webb22 dec. 2024 · In contrast to purely mechanical brakes eddy current brakes work only if there is motion. I.e. braking force depends not only on the magnetic field but also on the speed of the conductor moved through the field. They don't brake at all if everything is at rest; no matter how strong the field is (that's why they often are ideal for dampening). Webb1 feb. 2002 · Eddy current brakes only retard load lowering speeds, they will not stop a lowering load.
