Abstract

The invention relates to an axial-field permanent magnet compensated impulse generator with double contra-rotating rotors and belongs to the technical field of an impulse generator. The axial-field permanent magnet compensated impulse generator comprises a left rotor, a stator disc, a right rotor, two end caps and a shell. The left rotor, the stator disc and the right rotor are sequentially arranged in a hollow-square-shaped space formed by the two end caps and the shell along an axial direction. The left rotor along with one of the end caps and the right rotor along with the other end cap are in mirror symmetry on two sides of the stator disc. An air gap is formed between the left rotor and the stator disc, and another air gap is formed between the stator disc and the right rotor. The left rotor comprises a left rotor disc yoke, a left rotor permanent magnet, a left rotor compensation disc, a left rotor bandage, a left rotor shaft and a left rotor support. The stator disc comprises a stator support and a stator disc yoke. The double contra-rotating rotor compensated impulse generator is capable of solving the problem that the sizes of two motors are enlarged due to the fact that the two motors are arranged side by side and enabled to rotate reversely to counteract electromagnetic torque impact generated by the existing impulse generator during discharging.

Description

technical field [0001] The invention relates to an axial 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 of the m...
