研制用于空间的球形超声电机（SUSM）是本文的研究目标。SUSM是一种多自由度电机。在太空中使用马达必须扫清各种条件。为了验证SUSM对太阳辐射热的耐久性，本文在高温条件下进行了SUSM的驱动实验。因此，我们的SUSM在高温条件下保持了驱动性能。空间SUSM中使用的压电元件和胶粘剂材料是维持其空间驱动性能的重要因素。详细介绍了压电元件和胶粘剂的选择结果。
Development of spherical ultrasonic motor (SUSM) for space is an aim of this investigation. SUSM is a motor of multi-DOF. It's necessary to clear the various conditions to use a motor at space. In this paper, to confirm the durability to the radiant heat from the sun, drive experiments of SUSM was conducted in high temperature condition. As a result, our SUSM maintained the drive performance in high temperature condition. Materials of piezoelectric elements and of adhesives used in SUSM for space were important elements to maintain its drive performance in space. Selection results of the piezoelectric element and the adhesive were also reported in detail.
