Abstract

The invention relates to a flux switching type magnetic-concentration transverse flux permanent magnetic wind generator, in particular to a novel high-performance and direct-driving type transverse flux permanent magnetic wind generator. The generator comprises a stator, a rotor, permanent magnets and a winding. The stator consists of a plurality of stator cores (1) and an armature winding (5), wherein the stator cores (2) are distributed around the rotor. Two adjacent stator cores (1) in the circumferential direction are arranged in bilateral symmetry, and the stator cores are arranged on a casing (7) made from non-magnetic conductive material. Rotor cores (4) are arranged on a barrel (8) made from the non-magnetic conductive material. The barrel is connected with a motor rotary shaft (6), and is connected with a motor casing (7) through a bearing (9). Both sides of the rotor cores (4) are respectively embedded into permanent magnets (2) and (3), and the pole directions are opposite. The pole directions of the permanent magnets (2) and (3) of two adjacent rotor cores (4) in the peripheral direction are opposite. According to the motor structure, the single-phase generator can be manufactured, and the multiple-phase generator also can be manufactured.

Embodiment Construction

[0022] The magnetic flux switching type magnetic concentration type transverse flux permanent magnet wind power generator of the present invention is composed of a stator and a rotor. In order to make better use of the space utilization of the transverse magnetic flux, a permanent magnet with opposite magnetic poles is embedded at both ends of the rotor core, and the magnetization directions of the permanent magnets in the two adjacent rotor cores in the circumferential direction of each phase are opposite. The iron cores are stacked with silicon steel sheets with the same size, placed on a non-magnetic material cylinder to form the whole rotor. The permanent magnet in the rotor core is made of NdFeB material.

[0023] Each stator core is only made of silicon steel sheets, and the structure is simple. The size of each stator core is the same. The two adjacent stator cores in the circumferential direction of each phase are symmetrically arranged on the left and right, and place...
