  • Patent number: 6987368
    Abstract: A motor controller includes a position sensing device having a position sensor that senses a magnetic pole of a motor, a driver for driving the motor, and a wiring section that feeds a power supply voltage from the driver to the position sensing device. The position sensing device is equipped with a superposed-wave transmitter coupled to a first end of the wiring section and a serial converter for converting a signal of the sensing device into a serial signal. The driver is equipped with a superposed-wave receiver coupled to a second end of the wiring section and a parallel converter for converting the serial signal into a parallel signal. The foregoing structure allows superposing the information about switching a phase-excitation for driving the motor onto the wiring section formed of a pair of cables, i.e. two cables, so that the information is transmitted.

  • Patent number: 6882125
    Abstract: A motor controller includes a motor-position detector, a motor driver and a power cable having a pair of electric lines (two lines) which feeds power from the driver to the detector. The detector superimposes serial information about the motor-position to the power cable via windings of a transformer or a coupling capacitor. The serial information is obtained by converting parallel information about the motor-position. The serial information superimposed travels to the driver via the power cable. The driver receives the serial information via windings of the transformer or a coupling capacitor, and converts it to parallel information. The driver drives the motor according to this parallel information. The information necessary for driving the motor is superimposed to the power cable and transmitted through the power cable, so that a number of electric lines between the detector and the driver can be minimized.

  • Patent number: 5057062
    Abstract: A transfer case operation mode shifting apparatus used on a vehicle equipped with part-time four-wheel drive which having a center-differential shiftable between a differential-locked and differental-free drive mode of operation and between a two-wheel and a four-wheel drive mode of operation and a transfer shiftable between a high-speed range and a low-speed range drive mode of operation. The transfer case is shifted in its drive mode of operation by an operation mode selecting member for selecting a desired drive mode of operation. A power drive operation mode shifting device is provided in cooperation with the drive mode selecting member and a controller to actually shift the transfer case from one drive mode of operation to another. The controller is adapted to detect that the center-differential gear assembly of the transfer case is in a differential-locked four-wheel drive mode of operation so as to inhibit a transition of the center-differential to a two-wheel drive mode of operation.
