Three-Phase Induction Motor Totally Enclosed, externally ventilated, protection IP55, insulation class F with temperature rise class B, – Continuous operation-S1, Cage-type rotor in die cast aluminum or cast iron frame.
Mechanical and Construction Characteristics
A motor described in this catalogue are dimensioned according to IEC Standard.
Casing : Our motor casings from size 63 to 355 are in die cast iron. The aluminum frame upon request. Painting is blue.
Rotor: Cage rotor are made of aluminum (pressure die-cast method) The rotors are dynamically balanced (with the key inserted on shaft), in accordance with vibration rating N (IEC 34-14 Standard).
Stator Windings: The stators, assembled from magnetic sheet metal, are wound with
copper wire insulated with a double coating to class F standard. Windings are subjected to a special impregnation treatment with insulating paint, increase compactness and heat dispersion coefficients.
Vantilation : External and surface ventilation in provided by redial bi-directional fan blades installed on the opposite end of drive shaft, inside a fan cover made.
