    • The present invention provides a method for manufacturing a rigid internal gear for a wave gear device comprising an internally toothed portion and a gear main body portion comprised of different materials. In this method, a gear main body ring for forming a gear main body portion is preformed using a first aluminum alloy powder; an internal teeth-forming ring is preformed using a second aluminum alloy powder that has lower processability, is less durable, has higher abrasion resistance, and is harder than the first aluminum alloy powder; the internal teeth-forming ring is fitted inside the gear main body ring and the assembly is integrated by powder forging; and the resulting ring-shaped forging is subjected to post-processing, including cutting teeth. The gear main body portion and internally toothed portion are securely integrated by powder forging, and a lightweight rigid internal gear with high durability can therefore be obtained.
    • 本发明提供一种用于制造用于波齿轮装置的刚性内齿轮的方法,其包括内齿部分和由不同材料组成的齿轮主体部分。 在该方法中,使用第一铝合金粉末来形成用于形成齿轮主体部的齿轮主体环; 使用具有较低加工性,较不耐用,耐磨性更好并且比第一铝合金粉末更硬的第二铝合金粉末预成形内齿形成环; 内齿形成环安装在齿轮主体环的内部,组件通过粉末锻造结合; 对所得的环状锻造进行后处理,包括切削齿。 齿轮主体部分和内齿部分通过粉末锻造牢固地集成,因此可以获得具有高耐用性的轻质刚性内齿轮。

    • A synchronous machine control device includes a flux command generator, a magnetic flux estimator, a divider, a flux controller and γ- and δ-axis armature current controllers. The flux command generator produces a flux command from the synchronous machine turning speed. The magnetic flux estimator calculates the magnitude and phase of armature flux linkage from armature currents and field current taking into consideration magnetic fluxes produced by permanent magnets. The divider produces an armature current command by dividing a torque command by the armature flux linkage. The flux controller determines a field current command based on an error of the magnitude of the armature flux linkage from the flux command. The γ- and δ-axis armature current controllers control the synchronous machine such that both an error of an armature current in a direction perpendicular to the armature flux linkage direction from the armature current command and an armature current in the armature flux linkage direction become zeros.
    • 同步机控制装置包括磁通指令发生器,磁通量估计器,分频器,磁通控制器以及γ轴和δ轴电枢电流控制器。 磁通指令发生器从同步机转速得到磁通指令。 考虑到由永磁体产生的磁通量,磁通量估计器计算电枢电流和电流的电枢磁通量的大小和相位。 分压器通过将转矩指令除以电枢磁链来产生电枢电流指令。 磁通控制器基于来自磁通指令的电枢磁链的大小的误差来确定励磁电流指令。 γ轴和三角轴电枢电流控制器控制同步电机,使得电枢电流在与电枢电流指令的电枢磁通方向垂直的方向上的偏差和电枢磁链方向上的电枢电流均为零 。
