A Low Speed Direct Current Superconducting Heterpolar Motor.
Abstract
Important progress in assessing the limits of ratings for new concept electrical machines for ship propulsion applications has been achieved. The superconducting heteropolar motor has been identified as the most promising machine concept for slow speed, high power use. Maximum utilization of the drum homopolar machine is limited by transmission line current ratings, and may by greatly improved if an in-line drive is required, and thus allowing the use of the homopolar torque converter. The magnetic disc homopolar motor with water cooling appears to be the preferred concept for low speed homopolar motor applications. Technical progress in the conceptual configuration of the superconducting heteropolar machine is presented together with a report on progress on the solution of commutation problems in such machines.
