Radial magnetizing double-winding transverse flux permanent magnet generator

Abstract

The invention discloses a radial magnetizing double-winding transverse flux permanent magnet generator, comprising a stator and a rotor. The stator comprises two stator core groups. Each stator core group is composed of a plurality of stator cores which are uniformly distributed along a peripheral direction. Armature windings are arranged in winding slots of the stator core groups. The rotor comprises a plurality of rotor cores which are uniformly arranged along the peripheral direction. The rotor cores are arranged between the two stator core groups. Two pieces of permanent magnet with opposite polarities are embedded in each rotor core along a radial direction. The permanent magnet is magnetized radially. The polarities of the adjacent permanent magnet on the same periphery are opposite. According to the radial magnetizing double-winding transverse flux permanent magnet generator, the magnetizing directions of the permanent magnet on the same rotor core are opposite and the magnetizing directions of the adjacent permanent magnet on the same periphery are opposite; through combination of the feature that the stator cores f the two stator core groups are uniformly distributed along the peripheral direction, the condition that the permanent magnet is ineffective can be effectively avoided, a utilization rate of the permanent magnet in a motor can be improved, and the power density of the motor is improved; and the radial magnetizing double-winding transverse flux permanent magnet generator has the advantage of simple and reliable structure and convenient production.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motors, in particular to a radially magnetized double-winding transverse flux permanent magnet generator. Background technique [0002] In the context of the increasingly tense global energy sources, renewable and clean energy technologies are gaining more and more attention. As an important part of clean energy, wind power technology has developed rapidly in the world. It is estimated that by 2020, the total installed capacity of wind power in the world will reach 760GW. Wind turbine is the key core equipment of wind power system, and its electrical and mechanical properties directly affect the efficiency of wind energy conversion as well as the cost and reliability of the system. [0003] Due to the particularity of wind energy, wind turbines need to have good low-speed characteristics and high torque density characteristics at the same time. In a traditional radial wind turbine, the...
