Performance of disc-type brushless DC motor with single-phase winding

摘要

Permanent magnet motors become more and more popular machines nowadays mainly due to high-energy permanent magnets, which allow them to reach a very high performance. In the paper a newly designed disc-type brushless DC motor with a single-phase winding is presented. A motor operation and its performance are discussed on the basis of the characteristics obtained from the test carried out on the machine prototype. An attention is paid to converter the motor operates with and to special magnet arrangement that allows developing the starting torque.
