Abstract
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.
