NOVELTY - The module (70) has multiple permanent magnets (74, 75) inclined at an orientation that causes magnetic field to enter a portion of an outer surface (81) and to exit another portion of the outer surface. A magnetic keeper is removably coupled with the outer surface. A non-magnetic spacer is sandwiched between the magnetic keeper and the outer surface. A lamination stack (80) includes magnet receptacles and angled relative to each other. The permanent magnet is positioned in each of the magnet receptacles. An annular groove is formed on a portion of a sidewall of the lamination stack.    USE - Split-pole magnetic module for use in rotor of large permanent magnet machine (all claimed) e.g. permanent magnet generator for a wind turbine, a drive train product for a wind turbine, and an electrical machine for use in power generation and/or vehicle propulsion, motor, a generator such as multi-mega watt direct drive generators for wind turbines and medium speed multi-mega watt generators, an alternator and a dynamo. Can also be used for stator of an electrical machine.    ADVANTAGE - The module allows large permanent magnet machines such as generators and motors and use of two or more permanent magnets per split-pole magnetic module to reduce electrical e.g. eddy current losses in the permanent magnets and/or to allow use of permanent magnets of size that can be readily manufactured and/or handled. The magnetic keeper facilitates insertion of an assembled rotor of the modules coupled into a stator, thus eliminating manufacturing complexities and/or undesirable features. The module allows inclined orientation of the permanent magnets to concentrate magnetic flux to increase magnetic loading of a large permanent magnet machine, thus reducing machine's overall size for a given rating. The module allows magnetic fields and forces to be fully contained within the magnetic keeper, a fixture and/or stator structures during the assembly, thus improving safety for personnel.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing and/or assembling a split-pole magnetic module.
