Abstract
Способ пуска и бесщеточного возбуждения бесконтактной синхронной машины, согласно которому подают трехфазное переменное напряжение от внешней сети на обмотку статора, раскручивают ротор синхронной машины до подсинхронной скорости и подают напряжение на обмотку возбуждения синхронной машины от полупроводникового преобразователя, отличающийся тем, что статорную обмотку возбудителя подключают к внешнему источнику трехфазного переменного напряжения на минимальное число полюсов для раскрутки ротора, контролируют обороты ротора синхронной машины до достижения подсинхронной скорости и затем подключают статорную обмотку возбудителя к источнику постоянного напряжения на максимальное число полюсов, при этом величину постоянного напряжения устанавливают меньшей, чем действующая величина переменного напряжения.The method of starting and brushless excitation of a contactless synchronous machine, according to which a three-phase alternating voltage from an external network is supplied to the stator winding, the synchronous machine rotor is untwisted to a sub-synchronous speed and voltage is supplied to the excitation winding of the synchronous machine from a semiconductor converter, characterized in that the stator winding of the exciter is connected to external source of three-phase alternating voltage to the minimum number of poles for the rotation of the rotor, control the rotor speed sync In order to achieve subsynchronous speed, the stator winding of the pathogen is connected to a constant voltage source at the maximum number of poles, while the constant voltage is set lower than the effective value of the alternating voltage.
