Устройство генерирования стабильного напряжения переменного тока

Предлагаемая полезная модель относится к области электротехники и может быть использована при проектировании источников питания, применяемых в летательных аппаратах, судах и других автономных объектах. Магнитоэлектрический генератор приводится во вращение валом ведомой полумуфты магнитной трансмиссии, ведущая полумуфта которой связана с валом первичного двигателя с изменяющейся скоростью. Пропорционально изменению скорости ведомой полумуфты изменяется частота и напряжение на выходе генератора. Потребители электроэнергии рассчитаны на стабильное напряжение, но не критичны к частоте тока. Стабилизация выходного напряжения генератора осуществляется за счет регулирования скорости вращения ведомой полумуфты магнитной трансмиссии путем изменения частоты трехфазного напряжения, питающего обмотку трансмиссии. Частота трехфазного напряжения регулируется полупроводниковым устройством управления и определяется сигналом с выхода узла сравнения напряжения нагрузки с его заданным значением, определяемым источником задания напряжения. Техническим результатом, который достигается при использовании полезной модели, является увеличение надежности и уменьшение габаритов устройства генерирования стабильного напряжения переменного тока за счет упрощения его конструкции.

Die Erfindung betrifft ein Verfahren zur Bestimmung einer Position eines Rotors eines kommutierten Elektromotors, insbesondere für ein Kupplungsbetätigungssystem eines Fahrzeuges, bei welchem ein Signal des Rotors von einem Sensor abgenommen wird und hinsichtlich einer Position des Rotors ausgewertet wird. Bei einem Verfahren, bei welchem sowohl die Genauigkeit eines Absolutwertsignals als auch ein Rotor-zu-Stator-Positionssignal verbessert wird, werden aus einem Sensorrohsignal ein absolutes Positionssignal des Rotors für eine Sensorkalibrierung und eine Rotor-Stator-Position für eine Motorkommutierung ermittelt. The invention relates to a method for determining a position of a rotor of a commutated electric motor, in particular for a clutch actuation system of a vehicle, in which a signal of the rotor is taken from a sensor and evaluated with respect to a position of the rotor. In a method in which both the accuracy of an absolute value signal and a rotor-to-stator position signal is improved, an absolute position signal of the rotor for a sensor calibration and a rotor-stator position for a motor commutation are determined from a sensor raw signal.
