永久磁铁回转电机和风力发电系统
Abstract:
根据一实施方式的永久磁铁回转电机包括转子铁心(12)和定子铁心(13)。转子铁心(12)附接至旋转轴(11)并且具有永久磁铁。定子铁心(13)布置成在旋转轴(11)的径向方向上面向转子铁心(12)，并且具有槽(31)和绕线(32)。所述槽(31)设有绕线(32)。这里，绕线(32)以集中缠绕的方式来缠绕。此外，每极每相槽数q是满足下列关系表达式(A)的分数：1/4
Abstract(English):

The permanent magnet rotary electrical machine according to an embodiment includes a rotor core (12) and a stator core (13). The rotor core (12) is attached to a rotation shaft (11), and has permanent magnets. The stator core (13) is disposed to face the rotor core (12) in a radial direction of the rotation shaft (11), and has slots (31) and coils (32). The slots (32) are provided with coils (32). Here, the coils (32) are wound in a concentrated winding. Besides, the number of slots per pole and phase q is a fraction satisfying the following relational expression (A). 1/4
