中文摘要	A two-dimensional testbed that aims to demonstrate the feasibility of magnetically driving several spacecrafts was successfully constructed. The testbed has two vehicles, each of which consists of two Bi2223 coils placed in an orthogonal way. The magnetic force between the two vehicles with a 1 m separation distance is less than 1 N, which is big enough to attract, repel and rotate two 50 kg vehicles in a 1.2 m * 2 m platform. The hardware for the testbed, which includes the coils, a cryostat and an air pressured system, is introduced. A parallel power supply circuit was specifically designed for the high temperature superconductor (HTS) coil operating in space, for the purpose of reducing the Joule heat and providing redundancy. Two key questions relating to the HTS coil used in the magnetic driving are discussed. First, the magnetic force between the two coils, a preliminary index directing the coil parameters, is concisely expressed as an arithmetical equation. The accuracy of the equation is checked by a more accurate model based on the Biot-Savart law and a FEA calculation. Second, the interaction between the orthogonal coils with respect to the I/sub c/( B ) characteristic of the Bi2223 tape is discussed. A minimum safe distance between the two coils is defined and numerically calculated. Two coils whose separation distance is larger than the minimum safe distance can be regarded as having no magnetic interaction.
