Abstract

The invention discloses a hollow radial-magnetic-field permanent magnet opposite-rotating double-rotor compensation pulse electric generator, and belongs to the technical field of pulse electric generators. The hollow radial-magnetic-field permanent magnet opposite-rotating double-rotor compensation pulse electric generator aims at solving the problems that two electric generators are arranged in parallel at present and synchronously and oppositely rotate to counteract electromagnetic torque impacting generated during discharging of the pulse electric generators, and the sizes of the electric generators are enlarged accordingly. The hollow radial-magnetic-field permanent magnet opposite-rotating double-rotor compensation pulse electric generator comprises an outer rotor, an inner rotor and a stator. An inner rotor shaft and an outer rotor shaft are coaxial, the outer rotor, the stator and the inner rotor are sequentially and coaxially arranged from outside to inside, an outer air gap is formed between the outer rotor and the stator, and an inner air gap is formed between the stator and the inner rotor. An inner rotor yoke is fixed to the inner rotor shaft, an inner rotor permanent magnet is arranged on the outer circumference surface of the inner rotor yoke, and an inner rotor compensation cylinder and an inner rotor bandage are sequentially arranged on the outer circumference surface of the inner rotor permanent magnet; the magnetic field formed by the inner rotor permanent magnet and the magnetic field formed by the outer rotor permanent magnet are intersected with one side of a stator armature winding. The hollow radial-magnetic-field permanent magnet opposite-rotating double-rotor compensation pulse electric generator is a compensation pulse electric generator.

Description

technical field [0001] The invention relates to a hollow radial magnetic field permanent magnet counter-rotating dual-rotor compensation pulse generator, which belongs to the technical field of pulse generators. Background technique [0002] High-power pulse power supply can provide short-term strong pulse current, which is an important part of electromagnetic emission. The pulse generator based on inertial energy storage is a special synchronous generator, which greatly reduces the internal inductance of the armature winding by using the compensation principle and the magnetic flux compression principle, thereby obtaining a pulse current with a very high amplitude. Strong application potential. [0003] There are two main excitation methods for pulse generators: electric excitation and permanent magnet excitation. Because electric excitation requires brushes, the structure of the motor is complex, and the wear and ablation of the brushes will also reduce the reliability o...
