    • A brushless motor wherein rotating magnetic fields are generated in armature windings in a synchronous driving mode, outputting successively n kinds of driving waveshapes or the ones of a first pattern to an n-th pattern and thereafter, outputting the driving waveshapes again from the first pattern successively and circularly. When changing over the synchronous driving mode into a rotor position sensing driving mode, commutation signals (7u-7z) are changed over from the synchronous signals to the signals based on rotor position sensing signals (6u-6w), at a time to output the n-th pattern after outputting the (n-1)-th pattern. Thereby, when changing over the synchronous driving mode into the rotor position sensing driving mode, the order of the commutation signals are connected adequately to each other without adding particular adjunctive circuits and the transition between the modes can be performed smoothly.
    • 一种无刷电动机,其以同步驱动模式在电枢绕组中产生旋转磁场,连续输出n种驱动波形或第一图案的驱动波形到第n图形,然后再次从第一图案输出驱动波形 连续循环 当将同步驱动模式转换为转子位置感测驱动模式时,换向信号(7u-7z)根据转子位置检测信号(6u-6w)从同步信号切换到信号,以输出 输出第(n-1)个图案之后的第n图案。 因此,当将同步驱动模式转换为转子位置感测驱动模式时,换向信号的顺序彼此适当地连接,而不添加特定辅助电路,并且可以平滑地执行模式之间的转换。

    • A PWM converter includes a power source current detector (9), current instruction generator (7), current controller (6) and a main circuit power control section (8), and the current controller is constituted of comparators (17, 18, 19) which compare the line current measurement results with the line current instruction values, and a logic circuit (10) which generates switching instruction signals (PU, PV, PW) based on the comparison results with use of timing signals so that the switching power devices (Q1-Q6) are selectively turned ON and OFF in the direction of reducing the difference between the line current measurement results and the line current instruction values, and thus essentially solves the prior art problems associated with gain adjustment of current error amplifiers, which is completely adjustment-free and yet inexpensive.

    • Processing is started (S1), and control of each mounting processing is sequentially executed under a mounting program command in a storage section (S2). An electronic component is positioned on a mounting head, then taken out and held (S3). A BGA component is positioned by position detection of a reference mark and inspection, and correction is carried out in response to discrimination of holding attitude. In inspection using the reference mark as a reference position, the quality of the component is discriminated, for example, loss and shift of a solder bump and insufficiency of the quantity of the solder (S4). A normal component is moved to the vicinity of a mounting position on a printed board on a mounting table by the mounting head (S5). A recognition mark at the target mounting position on the printed board is confirmed and recognized (S6). The mounting position is corrected by mounting positioning based on the results of mounting position detection and component inspection (S7). The height of the mounting head is controlled and the component is mounted (S8). In response to the presence or absence of a mounting component, the processing shifts to processing S1 for continuation of processing, or shifts to processing S10 for end (S9) and the processing ends (S10).
    • 开始处理(S1),并且在存储部中的安装程序命令下顺序执行每个安装处理的控制(S2)。 电子部件位于安装头上,然后取出并保持(S3)。 BGA组件通过参考标记和检查的位置检测来定位,并且响应于对保持姿态的区分来执行校正。 在使用参考标记作为参考位置的检查中,鉴别焊料凸块的损耗和偏移以及焊料量不足的情况(S4)。 正常部件通过安装头移动到安装台上的印刷电路板上的安装位置附近(S5)。 确认并识别在印刷电路板上的目标安装位置处的识别标记(S6)。 基于安装位置检测和部件检查的结果(S7),通过安装定位来校正安装位置。 控制安装头的高度并安装组件(S8)。 响应于是否存在安装部件,处理转移到用于继续处理的处理S1,或者转移到结束处理S10(S9)并且处理结束(S10)。
