Latest Patents
Jonathan holds a patent for a "System for measuring the position of an electric motor." This electric system utilizes dynamic impedance changes in the windings of an electric motor to effectively measure and monitor mechanical position. The method employs a bridge amplifier to measure voltage at a center node or windings against a voltage derived from a reference network. When a winding of the motor is driven, it forms a voltage divider across the center node. Impedance changes in the windings occur as rotor poles pass by stator poles. The center node voltage varies with these impedance changes, and this variation corresponds to the measurement of rotational position. These measurements provide position and velocity feedback to a servo controller as long as current runs through a winding. This position sensing also applies to controlling commutation for brushless DC motors. Notably, impedance measurement uses normal motor-drive current for excitation without the need for additional sensing signals, extra "sense" windings, or external sensors. Jonathan has been granted 1 patent for this innovative technology.
