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.
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.
All DELPHI motors are
