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. |
