| Popis: | In this work the design of a homopolar motor prototype is proposed. The magnetic system consists of a high temperature superconducting (HTS) stator and a disc rotor with liquid metal sliding electric contacts made of gallium indium tin alloy. The estimation of magnetic fields and torques is performed for the device. The possibility of using this motor as a servo actuator is considered. The results of the preliminary experimental attempts to control a single pole motor based on permanent magnets by means of a proportional–integral–derivative (PID) algorithm are presented. |
