To provide a more efficient brushless electrical machine, as compared with conventional machines.
The brushless electrical machine (100a) is provided with a first member having a magnet assembly (10), and a second member having an electromagnetic coil (30). The first and second members are composed so that the positional relation between both can be changed. The magnet assembly (10) has a first magnet set (12) which is prepared in either the inner peripheral or the outer peripheral, and a second magnet set (14) prepared in the other side. The first and second magnet set (12, 14) are magnetized in opposite directions to each other so that same poles face each other, and produce the strongest magnetic field along a strong magnetic field direction connecting the inner circumference and the outer circumference of the magnet assembly (10).
