Title: Innovations by James A Wafer
Introduction
James A Wafer is a notable inventor based in Belleville, IL (US). He has made significant contributions to the field of electrical engineering, particularly in the development of switched reluctance machines. With a total of 3 patents to his name, Wafer's work showcases his expertise and innovative spirit.
Latest Patents
Wafer's latest patents include the "Segmented Stator Switched Reluctance Machine" and the "Sensorless Switched Reluctance Electric Machine with Segmented Stator." The segmented stator switched reluctance machine features a stator with multiple circumferentially-spaced stator segment assemblies, which include salient stator poles and inter-polar stator slots. Each assembly consists of a stack of stator plates forming a stator segment core, an end cap assembly, and winding wire wound around the stator segment core and the end cap assembly. The rotor, which defines several rotor poles, rotates relative to the stator to maximize the inductance of an energized winding. A drive circuit energizes the winding wire based on the rotor's rotational position. The sensorless switched reluctance machine operates similarly, but it utilizes a sensorless drive circuit to derive rotor position and energize the winding wire accordingly.
