Dual-12-pulse dual-flow brushless generator

Abstract

The invention discloses a dual-12-pulse dual-flow brushless generator. The dual-12-pulse dual-flow brushless generator mainly comprises a base, a DC generator stator, a DC generator rotor, a rotatingshaft, an alternating-current generator stator, an alternating-current generator rotor, an end cover, an exciter stator, an exciter rotor, a bearing, a rotary rectifier and the control system. The DCgenerator rotor, the alternating-current generator rotor, the bearing and the exciter rotor are fixedly installed on the rotating shaft in the base cavity in order from front to back, the DC generatorstator, the alternating-current generator stator, the end cover and the exciter stator are fixedly arranged in the base in order from front to back, the groove of the inner circle of the DC generatorstator is internally uniformly embedded with 4 sets of 3-phase windings, wherein the phase angles of the two sets of windings are 0-degree electric angle, the phase angles of the other two sets of windings are 30-degree electric angle, and the four sets of windings are output and then form four sets of direct currents through the rectifier to output. The dual-12-pulse dual-flow brushless generator is simple in structure and flexible in power supply feature, and has no interference of an excitation source and stable performances.

Description

technical field [0001] The invention relates to the field of production and manufacture of special motors, and specifically provides a double-12-pulse double-flow brushless generator. Background technique [0002] At present, there are two main modes of AC and DC power supply for aircraft ground power vehicles: one is to generate AC power from a three-phase AC generator driven by an internal combustion engine, and the DC power is to rectify the above-mentioned AC power through a transformer step-down , forming a DC power supply. This AC and DC power supply method has the following disadvantages. The output voltage of the DC power supply has no automatic adjustment function, and there is only a fixed DC voltage level, and the ripple of the DC part voltage is relatively large. The AC power supply and the DC power supply cannot be used at the same time. It is not suitable for working conditions where both AC and DC power supply are required at the same time. [0003] The othe...
