IEC Squirrel-Cage Motors
Recoding overview of Order No. from motor series 1LA7/1LA9 to 1LE1
Order No. code for motors 1LA7/1LA9
2 Siemens Supplement to Catalog D 81.1 · 2008
■
Overview
The Order No. comprises a combination of letters and digits and
for clarity it is subdivided into two blocks which are connected
by hyphens, e. g.:
1LA7113-4AA19-Z
M1F + A11 + G17
The first block (positions 1 to 7) identifies the motor type; further
characteristics of the version are coded in the second block
(positions 8 to 12).
For deviations in the second block from the catalog codes, either
-Z or 9 should be used as appropriate.
Ordering data:
• Complete Order No. and order code(s) or plain text.
• If a quotation has been requested, please specify the quota-
tion number in addition to the Order No.
• When ordering a complete motor as a spare part, please
specify the works serial No. for the previously supplied motor
as well as the Order No.
