Abstract

FIELD: electrical engineering; commutatorless motors with permanent-magnet rotors. SUBSTANCE: rotational electromotive force of de-energized motor winding is directly by means of difference integrator, and integration of inductance voltage of de-energized winding set up as result of dissipation of magnetic-field reactive energy stored in it is eliminated by means of reset pulse shaper. System has Schmitt flip-flop, trigger resistor, and difference integrator built around integrated Norton amplifier. EFFECT: improved noise immunity and system sensitivity in determining rotor position, increased efficiency and reliability, simplified design, and reduced cost of device.

Изобретение относится к электротехнике и может быть применено в бесколлекторных электропроводах, у которых ротор двигателя содержит постоянные магниты. Сущность изобретения заключается в прямом интегрировании ЭДС вращения незапитанной обмотки двигателя с помощью разностного интегратора и ликвидации интегрирования ЭДС самоидукции незапитанной обмотки, возникающей при рассеянии накопленной в ней реактивной энергии магнитного поля, с помощью формирователя импульса сброса. Введение триггера Шмитта увеличивает помехоустойчивость устройства. Наличие резистора запуска и выполнение разностного интегратора на интегральном операционном усилителе Нортона позволяет резко повысить чувствительность системы определения положения ротора, повысить КПД устройства и надежность устройства с его одновременным упрощением и удешевлением.The invention relates to electrical engineering and can be used in brushless electric wires, in which the motor rotor contains permanent magnets. The essence of the invention lies in the direct integration of the EMF of rotation of an uncharged motor winding with the help of a difference integrator and the elimination of the integration of the EMF of self-induction of an unpowered winding that occurs when the reactive energy of a magnetic field accumulated in it is dissipated using a reset pulse shaper. The introduction of a Schmitt trigger increases the noise immunity of the device. The presence of a start resistor and the implementation of a difference integrator on the Norton integrated operational amplifier allows you to drastically increase the sensitivity of the rotor position detection system, increase the efficiency of the device and the reliability of the device with its simultaneous simplification and cheapening.
