Motive motors are built according to international standard regulations; each size throughout the construction forms is calculated with reference to the tables of standard IEC 72-1.
All motors are multiple voltage multi-frequency 50/60Hz, F class insulation, (H on request) S1 continuous duty service, IP55 protection (IP56, 66, 67, and 68 on request) IE2 or IE3 efficiency class tropicalized winding suitable for inverter power supply
IE2, high efficiency class IE 60034-30
IE3, premium efficiency class IE 60034-30
Bearings selected for their silence and reliability and, for the same objectives, the cage rotor is dynamically balanced.
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
Motive asynchronous three-phase delphi series motors are closed, and externally ventilated. 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.
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
Cable gland can be easily moved on both the sides of the connection box, thanks to the screw cap The connection box can be rotated of 360° with steps of 90°
To protect them by the rust, motive motors are painted in silver RAL9006 colour
Performance excellence is granted by the low loss CRNO “FeV” magnetic laminations adoption,instead then the usual Semi Processed/Decarb “FeP01”.
