摘要：

High temperature superconductors have enabled us to construct non-contact levitation bearings for flywheel application. A flywheel with low loss bearing is important in energy storage for space applications where energy consumption and power consumption is carefully budgeted. It is interesting to know that a set of flywheels is commonly used for angular momentum storage for satellites pointing system. In this paper, we will discuss the design criterion on a small stable pointing system using levitation wheels. This is achieved by using superconductor magnet bearings which are passive, and virtually frictionless. We will also address frequently raised issues related to cooling requirement when using a cryocooler.
