    • Power requirements for a robotic system are achieved through the employment of modular-type linear motor (LM) cells of either the one dimensional or two-dimensional type. Increasing system power requirements are met through the utilization of an increasing number of modular linear motor cells precisely positioned upon a common mounting plate to assure proper operation with a common platen. Deviations in the planarity or flatness of the platen and/or linear motor confronting surfaces due, for example, to warpage, temperature fluctuations, machining considerations or the like, are accommodated by mounting each modular LM cell upon a solid suspension member having mounting legs which are machined or otherwise formed from the solid member so as to be compliant in the Z direction only and non-compliant in the mutually perpendicular X and Y directions thereby allowing for movement in the Z direction as well as rotational movement about the X or Y axes to compensate for warpage or non-planarity of the platen and/or linear motor. Each mounting leg has a boss which is provided to enable the compliant legs to undergo proper flexing due to the displacement of the adjacent mounting surface of the LM, provided for by the bosses.
    • 机器人系统的功率要求通过采用一维或二维型的模块式线性电动机(LM)单元实现。 通过利用越来越多的精确定位在公共安装板上的模块化线性电动机单元来满足增加的系统功率要求,以确保使用公共压板正确操作。 通过将每个模块LM单元安装在具有安装支脚的固体悬挂构件上来容纳由于例如翘曲,温度波动,加工考虑等导致的压板和/或线性电动机面对面的平面度或平面度的偏差, 被加工或以其他方式由实心构件形成,以便仅在Z方向上柔顺,并且在相互垂直的X和Y方向上不顺从,从而允许沿Z方向运动以及围绕X或Y轴的旋转运动 以补偿压板和/或线性电动机的翘曲或非平面性。 每个安装腿具有凸台,该凸台被设置成使得柔性腿能够由于由凸台提供的LM的相邻安装表面的位移而经历适当的弯曲。
