    • In a mechanical quantity measuring device (1) having a sensor chip (2) which outputs a sense output (S) corresponding to a mechanical quantity acting on the object to be measured (4), and a flexible wiring board (3) which supports the sensor chip (2) and has a wire (6) to lead out the sense output (S) to outside, and in which in measuring the mechanical quantity, the sensor chip (2) and the flexible wiring board (3) are attached to the object to be measured (4), a cutout (5) is provided on the flexible wiring board (3) near the sensor chip (2) and on the side where the wire (6) is arranged for the sensor chip (2). Thus, change in the sense output (S) with time can be restrained.

    • Provided are a brushless motor control device and a brushless motor system capable of preventing impossibility of intended control of a brushless motor resulting from false recognition that the brushless motor is in operation in spite of stoppage of the brushless motor. A brushless motor control unit calculates a voltage instruction, representing voltages to be applied to the brushless motor, according to a control instruction supplied from an upper control device. A position error calculation unit calculates and estimates a position error between d-q-axes and dc-qc-axes as rotational coordinate axes by use of the voltage instruction outputted by the brushless motor control unit, current values acquired by a coordinate transformation unit and revolution speed for control of the brushless motor. A fault detection unit judges whether the brushless motor is faulty or not based on the position error calculated by the position error calculation unit.
    • 提供一种无刷电动机控制装置和无刷电动机系统,其能够防止由于无刷电动机在无刷电动机停止的情况下运行中的错误识别而导致无刷电动机的预期控制。 无刷电机控制单元根据从上控制装置提供的控制指令,计算表示施加到无刷电动机的电压的电压指令。 位置误差计算单元通过使用无刷电动机控制单元输出的电压指令来计算和估计dq轴和dc-qc轴之间的位置误差作为旋转坐标轴,由坐标变换单元获取的电流值和转速 用于控制无刷电机。 故障检测单元基于由位置误差计算单元计算出的位置误差来判断无刷电动机是否有故障。
