Siemens SIMOTICS GP/SD 1LE1
Siemens SIMOTICS GP (aluminium frame) and SIMOTICS SD (cast-iron frame) standard induction motors, series 1LE1, in efficiency classes IE1–IE4, frame sizes from 63 to 315.
1LE1 is the series of standard three-phase induction motors in the Siemens SIMOTICS catalogue: SIMOTICS GP with aluminium frame (1LE1001 … 1LE1004) and SIMOTICS SD with cast-iron frame (1LE15.. for Basic Line and 1LE16.. for Performance Line); the frame sizes in the catalogue range from 63 to 315. In the catalogue overview table, the IEC variants have the classes: 1LE1001 IE2, 1LE1002 IE1, 1LE1003 IE3 and 1LE1004 IE4 (aluminium), and 1LE1501/1601 IE2, 1LE1502 IE1, 1LE1503/1603 IE3, 1LE1504/1604 IE4 (cast iron), respectively.
The article number has the form "1LE1503-1BB2■-■■■■": the fixed part corresponds, in the ordering tables, to a single row (power, size, number of poles), and the characters marked ■ in the catalogue are completed with the voltage, the mounting arrangement, the motor protection and the position of the terminal box. For a quotation request, send the complete code from the nameplate (it starts with 1LE1…), the voltage and the frequency; we confirm the code, the variants and the availability in the quotation.

Frequently asked questions
What efficiency class does a 1LE1 motor have?
For the IEC variants in the catalogue: 1LE1001 and 1LE1501/1601 are IE2, 1LE1002 and 1LE1502 are IE1, 1LE1003 and 1LE1503/1603 are IE3, 1LE1004 and 1LE1504/1604 are IE4. In the 1LE1503 tables some powers have a deviating IE class, marked separately in the catalogue; for a specific code we confirm the class in the manufacturer's documentation.
What is the difference between SIMOTICS GP and SD?
In the manufacturer's catalogue, GP has an aluminium frame (series 1LE10..), and SD has a cast-iron frame (series 1LE15.. and 1LE16..). The cast-iron series 1LE15.. is called Basic Line, and 1LE16.. Performance Line.
What details do I send for a quotation?
The complete code from the nameplate (including the suffix after "-Z", if any), the voltage, the frequency, the mounting arrangement (feet or flange) and, if the motor runs on an inverter, the inverter used. Made to order, the lead time is usually 1–4 weeks; we confirm the availability and the exact lead time in the quotation.
The listing is based on catalogue D 81.1 from 2018 and on the 1LE1503 tables at 400 V, 50 Hz; for other 1LE1 series, voltages or codes introduced later, we confirm the data from the manufacturer's current documentation, for the exact code.
