Rotors of electric motors EKV, EDKOF with copper-brass and aluminum rods of winding
In the construction of explosion-proof electric motors rotors of ECB type it is used rods in a rotor winding which are made of copper and brazed with copper short-circuiting rings.
Electric motors with such rotors have higher overload capacity, the efficiency increased due to reduction of losses in the copper rotor and energy saving.
A special feature of the EDCOF rotor construction is the rotor cell winding made of brass (upper cell) and copper (bottom cell) rods which are welded to copper short-circuiting rings. In such a design of the rotor winding the melting of the rods is eliminated in abnormal operating modes of the electric motor (frequent starts, overloads, load surges).
The sheets of active iron of the stator or rotor are made of electrical steel of 0,5-P-ShS-1-TO-Tsh-A-2212 grade GOST 2 1 4 2 7 2 - 8 3 for electric motors of the types: EDKVB, EKV, EDKO, BPM, VAO-2, DRT, and others.
The production of sheets is carried out by stamping with the use of KD-232E, KD-2122, KD-2318, KE-2330presses, etc.
