摘要：

The frequency dependence of the quench current of the epoxy-impregnated windings of a superconducting linear induction motor (SLIM) has been measured at f = 20 - 300 Hz; the quench current decreases with increasing frequency. The a.c. losses of SLIM windings have been measured and the temperature rise of the windings due to the a.c. losses studied by a numerical analysis using the finite element method. Reasons for the decrease in quench current with increasing frequency are discussed in relation to the a.c. losses.
