Abstract

Sposób rozruchu silnika polega na tym, ze ustala sie pierwsza graniczna wartosc dla pochodnej pradu i druga graniczna wartosc dla pochodnej pradu w uzwojeniu silnika, nastepnie dokonuje sie, w kazdym uzwojeniu roboczym silnika, pomiaru wartosci pochodnej pradu, po czym w oparciu o wyniki porównania zmierzonych wartosci pochodnych pradów w uzwojeniach roboczych silnika z ustalona pierwsza graniczna wartoscia dla pochodnej pradu oraz druga graniczna wartoscia dla pochodnej pradu dokonuje sie wyboru pierwszego uzwojenia do którego zalacza sie prad roboczy, natomiast kolejne przelaczenia uzwojen roboczych silnika dokonuje sie w zaleznosci od wybranego kierunku obrotu silnika oraz aktualnych wartosci dla pochodnych pradów w uzwojeniach roboczych silnika w relacji do wyznaczonych wartosci granicznych dla pochodnych pradu. Uklad rozruchu silnika reluktancyjnego ma blok pomiaru pochodnej pradu (6) polaczony z rezystorem pomiarowym, pierwszym komparatorem (2) oraz drugim komparatorem (3), które polaczone sa z blokiem regulacji i sterowania (1). Ponadto, pierwszy komparator (2) polaczony jest z blokiem pamieci pierwszej granicznej wartosci dla pochodnej pradu (4), natomiast drugi komparator (3) polaczony jest z blokiem pamieci drugiej granicznej wartosci dla pochodnej pradu (5).The method of starting the motor consists in determining the first limit value for the current derivative and the second limit value for the current derivative in the motor winding, then the current derivative is measured in each motor winding, and then based on the results of comparison of the measured values of derivative currents in the motor working windings with the first limiting value for the current derivative and the second limiting value for the current derivative set, the first winding to which the working current is connected is selected, while subsequent switching of the motor working windings is made depending on the selected direction of rotation of the motor and current values for current derivatives in the motor working windings in relation to the designated limit values for current derivatives. The reluctance motor starting system has a current derivative block (6) connected to a measuring resistor, first comparator (2) and second comparator (3), which are connected to the regulation and control block (1). In addition, the first comparator (2) is connected to the memory block of the first limiting value for the current derivative (4), while the second comparator (3) is connected to the memory block of the second limiting value for the current derivative (5).
