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.

The shapes built per IEC 34-7, are B3, B5, B14, B35.

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 160 the frame is made in cast iron.

All motors are:

   multiple voltage 230V/400V or 400/690V,
   and multi-frequency 50/60Hz,
   F class insulation,
   S1 continuous duty service,
   IP55 protection,
   1 or 2 class efficiency.

 
 
       
 
The copper is impregnated with a double layer of H class 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.
 
Aiming the maximum protecttion, the motors are equipped with tant details like the pull-resistant cable press and the combination of bearings with two shields each with rubber sealrings>
   
 


Cable press can be easily moved on both the sides of the connection box, thanks to the screw cap
 
motive motors adopt only bearings selected for their silence and reliability and, for the same objectives, the cage rotor is dynamically balanced according to IEC 34-14 and ISO 9921 norms.
 
 
 
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
 
Blocking the bearings into their slots with snap rings prevents them from moving axially. 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.
 
   
Performance excellence is granted by the FeV magnetic lamination sheets adoption, instead then the usual normal FeP01, FeV lamination sheets provide higher efficiency, lower heating, energy saving and longer life to isolation materials
 

Feet and connection box can be moved to the right or left
