  • Patent number: 11916456
    Abstract: A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.

  • Patent number: 9922586
    Abstract: A loading effect control device includes a detecting line, a detector, a load controller, and a gamma reference voltage generator. The detecting line is coupled to a first power supply line in a display panel, and the first power supply line provides a first power voltage. The detector measures the first power voltage in the display panel through the detecting line, detects an amount of load of the display panel, and outputs a first voltage corresponding to the detected amount of the load. The load controller determines a control amount of the load based on the detected load amount and a loading effect setting. The gamma reference voltage generator controls a gamma reference voltage based on the control amount of the load.
