Abstract
Inventia se refera la o schema de montaj pentru decomutarea electronica a înfasurarii statorice la motoare de putere mica comutate electronice. Scopul inventiei este acela de a comanda în asa fel amortizarea energiei de catre bobina însasi independent de frecventa de comutare si de curentul motorului, ca sa fie induse numai comutatoare, si de curentul motorului ca sa fie induse numai impulsuri mici definite ale tensiunii, iar curentul bobinei sa se apropie continuu si complet de zero. Acest scopse realizeaza, conform inventiei, prin aceea ca doi tranzistori se conecteaza între ei în asa fel încît coletorul unuia dintre tranzistori sa fie conectat la baza celui de-al doilea tranzistor, electrodul celui de-al doilea tranzistor sa fie conectatla baza primului tranzistor, iar doua tranzistoare sa fie intercalate între cîte o baza si un emitor al tranzistorului, si ca se conecteaza în asa fel încît în derivatie, prin intermediul unui element de cuplaj al unei înfasurari statorice, care sea fla legat în serie cu tranzistorii si rezistentele, încît elementele componente ale schemei de montaj - la comanda înfasurarii statorice - sa fie polarizate invers, adica în directia de blocare, de catre un tranzistor de comutare, cei doi tranzistoriprezentînd o succesiune diferita a zonelor.The invention relates to a mounting scheme for the electronic disconnection of stator winding in low-power electronic motors. The purpose of the invention is to control the damping of the energy by the coil itself independently of the switching frequency and the motor current to be induced only by the switches and by the motor current to be induced only by small defined pulses of voltage and the current the coil is continuously approaching and completely zero. According to the invention, this object is achieved by the fact that two transistors connect each other in such a way that the collector of one of the transistors is connected to the base of the second transistor, the electrode of the second transistor being connected to the base of the first transistor, and two transistors being interposed between a base and an emitter of the transistor, and that it is connected in such a way that by means of a coupling element of a stator coupling, sealed in series with the transistors and resistors, the components of the mounting scheme - upon command of the stator winding - are polarized backwards, ie in the lock direction, by a switching transistor, the two transistors presenting a different sequence of the zones.
