  • Serial printer with a linear motor printer carriage
    Patent number: 4445798
    Abstract: A serial printer is provided with a moving coil type linear motor operated printer carriage, wherein the magnetic field produced by a magnetic circuit of the linear motor is greatest at the opposite ends of the print stroke. The areas of increased magnetic field allow the printer carriage to be quickly accelerated up to the uniform speed at which printing takes place, as well as the deceleration of the carriage as it approaches the end of the print stroke.

  • Moving-coil linear motor
    Patent number: 4318038
    Abstract: A moving-coil linear motor suitable for driving a printer carriage of a serial printer is provided with a pair of coils disposed in side-by-side relationship. Logic circuitry is utilized to select which of the two coils should be energized, and in which direction current should flow through the coil in response to signals from a pair of magnetic field sensors mounted on the moving coil assembly.
