介绍了一种用于空间兼容偏振调制器的超导磁轴承旋转机构的设计及其机械和热性能。旋转机构由一个带有光学编码器的SMB和一个三把手机构组成，该机构保持悬浮转子，直到高温超导阵列（YBCO）冷却到临界温度以下。夹持机构的成功操作后，转子磁体悬浮在10-16 K，我们进行自旋下降测量。我们估计从转子旋转和光学编码器的散热。从机械和热性能的原型旋转机构，我们没有发现潜在的不去的结果，从这种SMB技术用于未来的空间使命。这种旋转机制的发展是针对使用的偏振调制器的空间使命探测漫画膨胀通过测量宇宙微波背景偏振。
We present the design and the mechanical and thermal performances of a prototype rotational mechanism using a superconducting magnetic bearing (SMB) for a space compatible polarization modulator. The rotational mechanism consists of an SMB with an optical encoder and a three-grip mechanism that holds a levitating rotor until a high-temperature superconducting array (YBCO) cools down below its critical temperature. After the successful operation of a grip mechanism, the rotor magnet levitates at 10-16 K, and we conduct spin-down measurements. We estimate the heat dissipation from the rotor rotation and an optical encoder. From the mechanical and thermal performances of the prototype rotation mechanism, we did not find the potential no-go results from this SMB technology for use in a future space mission. The development of this rotational mechanism is targeting for use of a polarization modulator for a space mission to probe the comic inflation by measuring the cosmic microwave background polarization.
