The copper is impregnated with a double layer of insulating enamel to ensure high resistance to electrical, thermal and mechanical stress. The phases are further isolated by another layer of Nomex film to protect the motors from the voltage peaks that usually occur when the motor is controlled by an inverter.
From type 90, a steel insert is provided in the bearing slot of the aluminum flanges, to resist to radial mechanical forces with a fair degree of security
Bearings selected for their silence and reliability and, for the same objectives, the cage rotor is dynamically balanced.
.The frame, up to 132 included, is made in die casting aluminium alloy, from size 160 up to 355 the frame is made in cast iron.
From size 160 and up, due to the high torque, the motors are fixed by feet that are diecasted with the iron frame
Aiming the maximum protection, the motors are equipped with important details like the pull-resistant cable gland and the combination of bearings with two shields each with rubber seal rings
la cassetta connessioni è predisposta per invertire con facilità la posizione del pressacavo
The connection box can be rotated of 360° with steps of 90°
To protect them by the rust, motive motors are painted
Performance excellence is granted by the low loss CRNO “FeV” magnetic laminations adoption, instead then the usual Semi Processed/Decarb “FeP01”. FeV laminations provide higher efficiency, lower heating, energy saving and longer life to insulation materials
From size 56 to size 132, feet are detachable, and can be fixed on 3 sides of the housing, thus permittig the terminal box to be positioned up, right or left.
