20140347075 | POSITION DETECTION DEVICE - A detection coil is incorporated in a self-oscillation circuit. The oscillation frequency of the self-oscillation circuit, which comprises the coil and a capacitor, is set to a high frequency band (e.g., around 1 MHz or higher). A target section whose relative position to the coil section varies in response to displacement of a detection object, and includes a magnetism-responsive member constructed to cause inductance of the coil to vary with the relative position. A rectifier circuit extracts an amplitude level of an oscillation output signal of the self-oscillation circuit and outputs the extracted level as detected position data. For example, a plurality of self-oscillation circuits are provided. Alternatively, a single self-oscillation circuit forms a plurality of series circuits by, for each coil pair, connecting in series the two coils of the coil pair, and includes the result of connecting the series circuits in parallel as an inductor element for self-oscillation. | 11-27-2014 |

20150130444 | POSITION DETECTION DEVICE - In a position detection device of a type that omits a secondary coil, various inconveniences arising from the use of a voltage-dividing resistance (fixed resistor) are eliminated. At least two pairs of coils are provided. A magnetism-responsive member are placed so as to effect relative displacement in relation to the coils, the relative position of the member in relation to the coils varies with a position of a detection object, and impedance of each coil is varied with the relative position. The impedance changes of two coils constituting each one of coil pairs present characteristics of mutually opposite phase characteristics. For each coil pair, the two coils constituting the pair are connected in series with each other, and from a connection point thereof, a voltage-divided output voltage according to the impedance of the two coils is taken out as a detection output signal for the pair. | 05-14-2015 |

20160131503 | INDUCTIVE POSITION DETECTION DEVICE - A coil section includes a primary coil which is magnetically excitable by an AC signal, and secondary coils which are provided so as to generate an inductive output in response to excitation of the primary coil. A self-oscillation circuit, including an inductance element and a capacitor, has incorporated therein the primary coil as the inductance element for self-oscillation. A target section is provided in such a manner that its relative position to the coil section varies according to a position of a target of detection, and the target section includes a magnetically responsive member disposed so that inductance of the secondary coils is varied according to the relative position. Amplitude levels of the output signals of the secondary coils are extracted, and position data of the position of the target of detection is obtained on the basis of these amplitude levels. | 05-12-2016 |
20160142001 | MOTOR CONTROL DEVICE AND MOTOR CONTROL SYSTEM - A motor control device includes: a control processing unit that controls driving of a motor based on a command signal input from a controller so as to command an operation of the motor and a detection signal which is a detection result of the operation of the motor; and an abnormality determining unit that detects an abnormality in the controller, the motor control device, and the motor based on the command signal, the detection signal, and a control signal generated in the motor control device and that determines a level of repeatability of the detected abnormality based on a predetermined criterion. The control processing unit transitions from a normal mode to a specific abnormality alarm mode when the abnormality determining unit determines that an specific abnormality having high repeatability has occurred. | 05-19-2016 |
