Abstract

The invention provides a self-excitation complete hollow passive compensation impulse generator, belonging to an electromechanical energy conversion device. The invention solves the problems of the existing small pulsed-power supply, including low power and energy density, no self-excitation without commercial power. A carbon fiber epoxy resin rotor yoke is fixed on a main shaft, a rotor excitation winding is adhered outside the carbon fiber epoxy resin rotor yoke, a carbon fiber ligation band is ligated and fixed outside the rotor excitation winding, an aluminum compensation sleeve is sheathed outside the carbon fiber ligation band; a composite stator yoke is fixed on the inner wall of the housing, a stator surface-wound armature winding is adhered on the inner wall of the composite stator yoke, a shielding box in the shape like the Chinese character 'HUI' is sheathed on the end portion of the stator surface-wound armature winding; an air space is arranged between the inner surface of the stator surface-wound armature winding and the outer surface of the aluminum compensation sleeve; the rotor is fixed inside the stator via two bearings; and one end of the main shaft is connected with a prime motor, and the other end thereof is fixed with a sliding ring and an electrical brush. The invention has the advantages of high energy storage and power density, small volume, and self-excitation.

Description

Technical field [0001] The invention relates to an electromechanical energy conversion device. Background technique [0002] Rotating machinery used as high-power pulse power supply currently mainly includes unipolar generators, synchronous generators and compensated pulse generators. [0003] The main disadvantage of a unipolar generator is that the voltage is too low. Although a synchronous generator can generate a higher voltage, it needs to increase the exciting magnetic field, or increase the speed, or increase the number of turns N of the armature winding. The first two factors are limited by the physical properties of the materials used, and increasing N will make the winding coil inductance change with N 2 Increase, this will cause the voltage rise time of the synchronous generator to be too long, and the discharge current rise time is too long. [0004] In 1978, the compensating pulse generator invented by the University of Texas Electromechanical Research Center WFWeldo...
