A brushless motor capable of increasing energy density by effective
utilization of reluctance torque. The brushless motor comprises a stator
(5) and a rotor (1) having a lateral surface opposed to the stator (5).
The stator (5) comprises a plurality of radially extending iron cores (10)
and a plurality of windings (11) for generating a magnetic field in each
iron core (10). The rotor (1) comprises a plurality of permanent magnets
(2) and a magnetic field line inducing body disposed between each
permanent magnet (2) and the lateral surface.
