Experimental study of thrusts of a cylindrical linear synchronous motor with an HTS coil magnet as the excitation system
چکیده انگلیسی


• Thrusts of a cylindrical linear synchronous motor with an HTS coil were measured.
• Effects of armature current, coil current and running time were studied.
• Thrusts of HTS coil with magnetizers were studied.
• Effect of seams between magnetizers was studied.

The thrusts of a cylindrical linear synchronous motor with an HTS coil magnet as the excitation system were measured the first time and will be presented in this paper. The HTS coil magnet is made of second generation YBCO wire. The coil is a double pancake coil consisting of 34 turns wire. The inner diameter, outer diameter and height of the coil are 20, 30 and 13 mm, respectively. The armature of the motor is three phases, and the inner diameter is 40 mm. It is made of copper windings. With a direct current of 40 A for the HTS coil magnet and a RMS current of 10 A for the armature, a peak thrust of 3.8 N was measured at the temperature of 77 K and a radial gap of 5 mm between the armature and the excitation system. Effects of armature current, coil current, running time, magnetizers and seams between magnetizers were also studied. In the experiments, the peak thrusts of different types of HTS coil magnets were about from 1.3 times to 8 times as strong as the peak thrust of the coreless coil magnet under the same conditions.
