摘要： A magnetic component (10) including first and second regions (20, 30), and a method of varying the magnetization values in different regions of the magnetic component are disclosed. The first and the second regions are characterized by a nitrogen content that is different from each other. At least one of the first region and the second region is partially-magnetic and has a nitrogen content in a range from about 0.1 weight % to about 0.4 weight % of that region. A concentration of carbon, if present, of both the first and second regions is less than about 0.05 weight% of the respective regions.

摘要： A permanent magnet electrical machine includes a stator 12 having conductive windings wound thereon and one or more permanent magnets 26 embedded in the stator. A magnetic keeper element 34 is positioned on the stator so as to form a magnetic flux path with the permanent magnets, with the magnetic keeper element 34 closing the magnetic flux path of the permanent magnets 26 by providing a low reluctance flux path to magnetic flux generated by the permanent magnets. A vacuum pressure impregnation (VPI) process is performed on the stator 12 to increase a thermal conductivity of the windings, with the VPI process including a curing step that is performed at a selected temperature. The magnetic keeper element 34 sets an operating point of the permanent magnets to an internal flux density level above a demagnetization threshold associated with the selected temperature at which the curing step is performed.

摘要： A magnet management method (100) of controlling a ferrite-type permanent magnet electrical machine includes receiving and/or estimating the temperature permanent magnets (110); determining if that temperature is below a predetermined temperature (112); and if so, then: selectively heating the magnets in order to prevent demagnetization (114) and/or derating the machine (116). A similar method (200) provides for controlling magnetization level by analyzing flux or magnetization level. Controllers that employ various methods are disclosed. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.
