Aeroengine nozzle side fault-tolerant generator

Abstract

The invention relates to a fault tolerant generator at the nozzle side of an aerial engine, and belongs to the field of aircraft engineering. The fault tolerant generator comprises an excitation coil,an excitation iron core, a rotor iron core, an armature coil and an armature iron core; the rotor iron core is fixed at one side of the nozzle of the low-pressure shaft of the aerial engine; the excitation iron core and the armature iron core are separately positioned at two axial sides of the rotor iron core; 12 fan-shaped through holes are uniformly distributed on the circumference of the rotoriron core; 10 fan-shaped protruding excitation poles are at one side of the excitation iron core towards the rotor iron core; 10 fan-shaped protruding armature poles are at one side of the armature iron core towards the rotor iron core; a centralized excitation coil is wound on each excitation pole; and a centralized armature coil is wound on each armature pole. According to the fault tolerant generator disclosed by the invention, the rotational inertia of the rotor iron core is low; therefore, the rotor iron core can rotate at high speed; and thus, the rotor iron core is particularly suitable for the fault tolerant generator at the nozzle side of the aerial engine.

Description

technical field [0001] The invention relates to a fault-tolerant generator at the nozzle side of an aero-engine, belonging to the field of aeronautical electrical engineering. Background technique [0002] More electric aircraft and all-electric aircraft are the inevitable trend of modern aircraft development. Having a starter generator is an important feature of a multi-electric aircraft. On the basis of the traditional aviation gas turbine engine, the magnetic suspension bearing for the built-in starter generator to support the engine rotor is installed inside the aircraft engine, eliminating the need for a transmission mechanism and running at a high speed. Provide sufficient power to supply components such as distributed electronic control systems, electric fuel pumps and electric actuators. [0003] With the development of science and technology, motors have been more and more widely used in military and civilian fields. However, aerospace and other fields that have hi...
