Abstract:
An electricity generator exhibiting a functioning air gap radius extending from a generator axis, and drivably operable to generate maximum current, comprising:a rotor having a sequence of generally arcuate regions of predetermined magnetization and confronting magnetic surface of principal dimension in parallel with said generator axis, said confronting magnetic surface being located in correspondence with said air gap radius and rotatable about said generator axis; a stator core assembly having a select number of spaced core components formed of pressure shaped processed ferromagnetic particles which are generally mutually insulatively associated, each said core component being disposed about a radius extending from said generator axis, having a flux interaction surface located adjacent said rotor confronting magnetic surface defining an air gap and having a face length parallel with said generatorr axis and a face width selected to provide a magnetic field coupling, each said core component having a winding support region spaced from and in flux transfer communication with said flux interaction surface, having a winding region width generally normal to said radius and cross-sectional area attributes effective for conveyance of confronting magnetic flux without saturation when said generator is driven to generate said maximum current, and said stator assembly including a back iron assembly formed of pressure shaped processed ferromagnetic particles which are generally mutually insulatively associated, said back iron assembly being in flux transfer association with each said core component adjacent said winding support region and having cross-sectional area attributes effective for magnetic flux conveyance without saturation, said face width having a value less than about 2.5 times said winding region width; and a field winding assembly including winding components located at each said core component and extending in electromagnetic flux coupling relationship about said winding support region, said winding components being electrically coupled with a generator output for providing generated current upon driven rotation of said rotor about said generator axis.
