Abstract :
The paper describes a novel permanent magnets brushless machine with double-gap, two rotors and axially aligned stator poles. The stator coils are separated from each other to encourage airflow around the conductors for more effective cooling and to separate the phases. Finite element analysis is used to determine the electromotive force. The new configuration provides numerous advantages in comparison with classic construction: lower weight, lower permanent magnet weight, higher efficiency, better cooling, lower inertia.
