Abstract

The invention belongs to the field of pulse power generators and discloses a permanent-magnet axial-flux semi-hollow pulse power generator comprising a rotor, a stator, a rotating shaft, a housing, and an end cap. The rotor comprises inner and outer magnetic poles, a permanent magnet and a compensation plate. The permanent magnet is arranged between the inner and outer magnetic poles of the rotor. The inner and outer magnetic poles cooperate with the permanent magnet to convert radial flux into axial flux. The compensation plate covers the tops of the inner and outer magnetic poles. The rotor rotates together with the rotating shaft. The stator is formed by pouring non-magnetic material on a winding and is fixed on the housing. The magnetic conductive material of the rotor and the non-magnetic conductive material of the stator form a semi-hollow structure. The semi-hollow pulse power generator simplifies a motor excitation system, reduces excitation loss, and increases motor efficiency. Brushless structure increases the reliability of the motor.

Description

technical field [0001] The invention belongs to the field of pulse generators, and more specifically relates to a semi-hollow pulse generator with permanent magnet axial flux. Background technique [0002] As a pulse power supply integrating inertial energy storage, electromechanical energy conversion, and pulse shaping, pulse generator has attracted people's attention since its inception, and is widely used in scientific research, industry and military fields. It has experienced the development process from solid rotor to hollow rotor, from no compensation to compensation. [0003] When the stator and rotor of the pulse generator adopt a hollow structure, that is, there is no ferromagnetic material, although a lower transient inductance and a higher air-gap magnetic density can be obtained during discharge, it also makes the excitation system more complex and brings Larger excitation loss, the brushes that energize the rotor excitation winding will also reduce the reliabil...
