Several superconducting ac machine concepts were studied for ship propulsion applications. These concepts evolved from previous work at MIT on superconducting ac machines. The superconducting machines considered were: (1) multipole, low-speed motors, (2) torque compensated motors, (3) high-speed generator, (4) rotating air-gap armature induction motor, (5) thyristor switched ac motors. The first four machine types were studied theoretically while experimental models were constructed of the last two. Preliminary designs were completed for each of the five mahcines for an appropriate ship propulsion application. In addition a theoretical study of the refrigeration requirements for ac superconducting machines was performed.
