Abstract

The invention discloses a brushless excitation air core pulse generator, which belongs to the technical field of generators. The brushless excitation air core pulse generator, in the structure, comprises an air core stator base, an air core rotor base, a generator excitation winding, a generator armature winding, an exciter armature winding, an exciter excitation winding, a rotation shaft, a binding sleeve, a housing and an end cover. The brushless excitation air core pulse generator is divided to two parts of the generator and the exciter; the rotor winding is formed by the generator excitation winding and the exciter armature winding and is integrally cast through epoxy resin and is connected with the air core rotor base, and both are multi-phase windings and are in negative-phase-sequence connection. Thus, the frequency of the armature winding of a magnetic field cutting generator in a generator can be improved, the induction potential of the generator armature winding can be increased, the air core pulse generator is brushless, the whole reliability and the safety of the motor are improved, the excitation current upper limit is increased, and the energy storage density and the power density of the motor can be improved.

Description

technical field [0001] The invention belongs to the technical field of generators, and more specifically relates to a brushless excitation air-core pulse generator. Background technique [0002] As a special pulse power supply, the pulse generator integrates inertial energy storage, energy conversion and pulse regulation. It has the advantages of high energy storage density, high power density, high repetition frequency and long service life, and has a wide range of applications. Prospects have important scientific significance in scientific research, national defense technology, industry, medicine, environmental protection and other fields. [0003] Pulse generators use energy storage density and power density as indicators. In order to increase the energy storage density and power density, the stator and rotor of the pulse generator are generally made of air-core materials (that is, non-magnetic materials). Although the high magnetic permeability of ferromagnetic materia...
