Abstract

The invention relates to a parallel-structure brushless hybrid excitation synchronous generator based on harmonic winding excitation. The synchronous generator comprises an electric excitation part and a permanent magnet part which are arranged in parallel, wherein the electric excitation part is of an integer slot structure, a stator core of the electric excitation part is provided with a plurality of grooves in the circumferential direction, and each groove is internally provided with a first motor stator armature winding and a stator harmonic winding; a rotor core of the electric excitationpart comprises main teeth and branch teeth, the branch teeth are arranged at the ends of the main teeth, the main teeth are sleeved with rotor excitation windings, and the branch teeth are sleeved with rotor harmonic windings; and a permanent magnet is attached to the surface of the rotor core of the permanent magnet part. Brushless parallel-structure hybrid excitation is realized by adopting a harmonic winding excitation mode, it is convenient to realize excitation adjustment, electric excitation and permanent magnet flux paths can be mutually decoupled, and the control mode is simple.

Description

technical field [0001] The invention relates to the technical field of hybrid excitation synchronous motors, in particular to a parallel structure brushless hybrid excitation synchronous generator based on harmonic winding excitation. Background technique [0002] Synchronous motors have excellent characteristics such as high power density and high efficiency, and are widely used in industrial fields such as electric vehicles, wind power generation, and automated manufacturing equipment. However, there are always three problems to be solved in the permanent magnet synchronous motor: (1) the excitation flux generated by the permanent magnet is difficult to adjust; (2) the permanent magnet material has the risk of demagnetization and the motor cannot work; (3) as the permanent magnet The increasingly widespread application of magnetic materials leads to their high prices and the need to reduce their usage. Hybrid excitation motor with high power density of permanent magnet mo...
