  • Patent number: 9160219
    Abstract: Disclosed is a brushless motor (1A) which is an axial gap type brushless motor (1A) wherein stators (3A, 4A) comprising a coil (41) and a rotor (2) comprising a permanent magnet (23) are arranged with a gap therebetween in the axial direction. The coil (41) is a band-like wire which is spirally wound such that the width direction of the band-like wire generally coincides with the direction of the magnetic flux that is generated by the permanent magnet (23) of the rotor (2). Consequently, the axial gap type brushless motor (1A) having the above-described structure can be further reduced in eddy current loss in comparison to conventional brushless motors.
