IEC Squirrel-Cage Motors
Recoding overview of Order No. from motor series 1LA7/1LA9 to 1LE1
Order No. code for motors 1LE1
3
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.: 
1LE1001-1DB20-1AA5-Z
H00
The first block (positions 1 to 7) identifies the motor type; the 
second block (positions 8 to 12) defines the motor frame size 
and length, the number of poles and in some cases the 
frequency/output; and in the third block (positions 13 to 16), the 
frequency/output, type of construction and other design features 
are encoded.
For deviations in the second and third blocks 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 
quotation 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.
