  • Winding pattern of a motor and a motor driving system
    Patent number: 11967862
    Abstract: In a driving system, first and second inverters are connected to a driving motor, one end of a stator winding through which 3-phase current flows is connected to an output line of the first inverter, and the other end of the stator winding is connected to an output line of the second inverter. A winding pattern of the driving motor includes: coils wound in slots defined in the stator and to which 3-phase current is applied; coils wound on innermost and outermost sides based on a direction toward a rotating shaft of the driving motor in the slots, and being energized by different AC phases; and coils disposed between a first coil located on the outermost side and a second coil located on the innermost side, and being energized by the same AC phases as those of the first and second coils.

  • System and method for analyzing and/or estimating state of banknote processing apparatus
    Patent number: 9406184
    Abstract: There are provided a system and a method for analyzing and/or estimating a state of a banknote processing apparatus. The system includes an information detector configured to detect use information of the banknote processing apparatus in real time, a state estimating apparatus configured to produce statistical information based on the detected use information and produce state estimation information on a state of the banknote processing apparatus and/or an operating environment of the banknote processing apparatus using the statistical information, and a database configured to store one or more of the use information, the statistical information, and the state estimation information.
