Title: The Innovations of Frank W Stellwagen
Introduction
Frank W Stellwagen is a notable inventor based in Stamford, CT, who has made significant contributions to the field of electrical engineering. He holds three patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on low power synchronous motors, which have practical applications in various devices.
Latest Patents
One of Stellwagen's latest patents is for a low power synchronous motor and line cord. This invention features a rotor that includes a pair of rotor discs with a permanent magnet sandwiched between them. The magnet is polarized, creating a north pole on one rotor disc and a south pole on the other. The stator of the motor includes an energizing winding with a core passing through it. Complementary stator plates are secured at each end of the winding, bent at right angles to form a coplanar stator air gap portion. This design allows for easy assembly of the motor in clock movements. Additionally, the electrical energy coupled to the energizing winding is managed by impedance elements that reduce current flow, preventing hazardous shocks from exposed wires.
