<p>A generator. An external stator (3) of the generator includes a ring-type iron core (31) and a winding (32). In the axial direction, the iron core (31) includes a number of outer slots (312) and a number of inner slots (311) with equal slot width (W1) and equal slot depth. The winding (32) is continually wrapped around the inner slots (311) and the outer slots (312) of the external stator (3). Pairs (41) of excitation magnets are symmetrically fixed on a rotor (4) of the generator along a center shaft (2). Facing the inner slots (311), the polarities of magnetic poles of two excitation magnets (411,412) included in each pair (41) of the excitation magnets are opposite to each other. Between two excitation magnets (411,412) included in each pair (41) of the excitation magnets, there is a certain interval. Every excitation magnet (411,412) has a certain thickness. When the rotor (4) is rotating, while one excitation magnet (411,412) included in each pair (41) of excitation magnets is passing through a position under one inner slot (311), another excitation magnet (411,412) included in each pair (41) of excitation magnets will not pass though positions under anyone of the slots (311).</p> |
