Latest Patents

Jean-Luc Passello holds a patent for a "Method and apparatus for driving a stepping motor using digital pulse." This invention involves generating first pulses at multiple levels, simulating sinusoidal waves to drive the motor effectively. The method ensures that the maximum level is applied during two consecutive microsteps to one phase of the motor, while the other phase alternates in sign. This technique allows for precise stopping positions, maintaining a whole number of half steps between them. As a result, the printing process becomes very precise, fast, and noise-free, effectively doubling the resolution without sacrificing speed or accuracy.
