摘要： A method and devices to redistribute magnetic flux density within electro-magnetic or permanent magnet devices to increase utilization of magnetic core material and increase its power density. Magnetic core bias currents, synchronized to the device's magnetizing current, through uniform, longitudinally isolated, magnetic core sections are used. Local core bias currents that generate magnetic flux that oppose the incident magnetizing flux in local magnetic core sections with high flux density concentrations such as core corners may be added. Examples of the types of electro-magnetic and permanent magnet devices that benefit from the appropriate application of magnetic flux density redistribution include electrical devices such as transformers, inductors, delay lines, and electromechanical devices such as motors, generators, relays, solenoids, and rail guns.

摘要： A method and devices to redistribute magnetic flux density within electro-magnetic or permanent magnet devices to increase utilization of magnetic core material and increase its power density. Magnetic core bias currents (291, 292), synchronized to the device's magnetizing current, through uniform, longitudinally isolated, magnetic core (302, 301) sections are used. Local core bias currents (292) that generate magnetic flux that oppose the incident magnetizing flux in local magnetic core sections with high flux density concentrations such as core corners may be added. Examples of the types of electro-magnetic and permanent magnet devices that benefit from the appropriate application of magnetic flux density redistribution include electrical devices such as transformers, inductors, delay lines, and electromechanical devices such as motors, generators, relays, solenoids, and rail guns.
