Micro-turbo generator device

Abstract

A micro-turbo generator device (10) includes a housing (12), a rotor (14), a plurality of stator cores (16), and coils (18) encircling the stator cores. The housing (12) includes a shaft (34) which has an axis (11). The rotor (14) is rotatably mounted onto the shaft (34) and includes a perimeter (32) and a plurality of rotor poles (24) extending generally radially about the axis (11). Each rotor pole (24) includes a magnetizable tip (30) and a concave fluid impact surface (26). The stator cores (16) are disposed about the rotor (14) and include first pole face (15) and second pole face (17) facing the perimeter (32) of the rotor (14) and spaced apart therefrom. The coils (18) helically encircle the stator cores (16) and conduct electrical current to magnetize the stator cores (16) to magnetize the tips (30) and to alternately conduct induced electrical current generated in response to changes in magnetic flux between the first and second pole faces (15, 17) and the magnetizable tips (30).
