Abstract
Inventia se refera la un motor electric asincron frîna cu rotor în scurtcircuit si dubla actiune, la care cîmpul magnetic propriu genereaza simultan atît cuplul de rotatie motor asupra rotorului, cît si forta electromagnetica pentru deblocarea frînei. Motorul, potrivit inventiei are un sistem constructiv cu un pachet rotoric sa care se distinge o zona normala prelungita cu o zona modificata, zona modificata a pachetului rotoric fiind constituita din tole care au doua rînduri de crestaturi dispuse concentric, un rînd la nivelul crestaturilor din zona nemodificata si altul sub primul rînd. Cele doua rînduri de crestaturi ale zonei modificate a pachetului rotoric comunica între ele si creeaza astfel o asazisa colivie sau o colivie cu bare înalte. Barele coliviei rotorice din zona pachetului rotoric normal se continua cu barele gen dubla colivie sau colivie cu bare înalte din zona pachetului rotoric modificat, care se scurtcircuiteaza cu un inel de scurtcircuitare numai în zona corespunzatoare rîndului interior de crestaturi ale pachetului rotoric modificat. Forta electromagnetica de atractie axiala, necesarii deblocarii frînei, este generata de efectul combinat al fluxului magnetic creat de curentul care strabate inelul de scurtcircuitare de pe partea modificata a pachetului rotoric si al fluxului magnetic creat de înfasurarea de excitatie statorica în zona pachetului rotoric modificat, în fata caruia este dispusa, pe arborele motorului, armatura mobila de deblocare a frînei.The invention relates to an asynchronous electric motor with a short-circuit rotor and a double action, in which the magnetic field itself generates both the motor rotation torque on the rotor and the electromagnetic force for unblocking the brake. According to the invention, the engine has a constructive system with a rotor pack which distinguishes a normal extended area with a modified area, the modified part of the rotor package being constituted by troughs having two rows of notches arranged concentrically, one row at the notches in the area unmodified and the other in the first place. The two rows of ridges of the modified rotor area communicate with each other and thus create a cage or a cage with high bars. The rotor cage bars in the normal rotor bay area continue with double-cage or high-bay bars in the modified rotor bay area, which short-circuit with a short-circuit ring only in the area corresponding to the internal rotation row of the modified rotor bundle. The electromagnetic force of axial attraction required to unlock the brake is generated by the combined effect of the magnetic flux created by the current passing through the rotor ring and the magnetic flux created by the stator excitation in the area of the modified rotor packet the face of which is arranged on the motor shaft, the mobile release brake release armature.
