Latest Patents

One of Gauthier's latest inventions is the "2-Pole single or dual coil moving magnet motor with moving back iron." This innovative motor design features a moving magnet that is integrally attached to the back iron flux return path. The motor utilizes a two-pole fixed stator with energizing coils wrapped around each pole. The application of current to these coils generates a magnetic field that propels the moving magnet and back iron combination. This invention is particularly advantageous for use as a disc drive read/write head positioning actuator, as it reduces the size of the positioner and simplifies the overall design. An improvement on this design involves embedding the permanent magnet into the back iron, further minimizing the motor's size.

Another significant patent is the "Closed loop single step response by open winding voltage feedback system." This system provides a method for controlling the step response of a multiple-phase step motor. By minimizing rotor oscillation amplitude, the invention enhances data acquisition speed in computer memory disc drives by reducing settling and seek times. The method involves sampling back emf voltage across an open phase winding to produce a continuous feedback signal, which is then applied to an energized phase winding for damping. This innovation eliminates the need for external sensors or complex electronics.
