This paper describes a series of experiments to investigate the operational characteristics of a superconducting fluxpump with a superconducting excitation coil. In this experiment, the idea of excitation in the fluxpump is introduced to control the pole-flux in the air gap of the machine. The operating current of the fluxpump is designed to have the value of 300 amps. for the rotational speed of 600 rpm. Sensors installed on the Nb sheet yield the information on the spatial and temporal behaviors of the magnetic field in spot and on the characteristics of the fluxpump. The experimental observations are compared with the theoretical predictions.
