1LE1 motor generation

These "recommendations for drive selection" guide you step-by-step through this catalog to the required motor.

Step 1	Technical requirements for the motor
Determine the required product profile, the following are required:	Rated frequency and rated voltage	3 AC 50/60 Hz, 400, 500 or 690 V
	Duty	Standard duty (continuous duty S1 according to DIN EN 60034-1)
	Degree of protection required	IP..
	Rated speed (No. of poles)	n =................. rpm
	Rated output	P =................. kW
	Rated torque	M = P · 9550/n =................. Nm
	Type of construction	IM..
Step 2	Environmental requirements for the motor
Determine the installation conditions	Ambient temperature	? 40 °C	>40 °C
	Site altitude	?1000 m	>1000 m
	Factors for derating	None	Determine the factor for derating (for derating factor, see "Technical information" – "Coolant temperature and site altitude")
Step 3	For preliminary selection of the motor ? see subsequent pages and the corresponding "Preliminary selection of the motor" tables
Determine the range of possible motors	Select the frame size and therefore the possible motors on the basis of the following parameters: cooling method, degree of protection, rated output, rated speed and rated torque range. Note: The standard temperature range of the motors is from -20 to +40°C.
Step 4	Detailed selection of the motor
Determine the basic Order No. of the motor	Determine the motor Order No. according to the following parameters: rated output, rated speed, rated torque and rated current from the "Selection and ordering data" for the motors that have already been identified as possibilities.
Step 5	Selection of the special versions (see under "Special versions")
Complete the motor Order No.	Determine special versions and the associated Order codes (e.g. special voltages and types of construction, motor protection and degrees of protection, windings and insulation, colors and paint finish, mountings and mounting technology, etc.).
Step 6
Select the frequency converter, if required	For Order No. of the converter as well as its selection, see Catalogs D 11, D 11.1, DA 51.2 and DA 51.3.

Order No. code

The order number consists of a combination of figures and letters and is divided into three blocks linked with hyphens for a better overview, 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 block from the catalog codes, either -Zor9 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.

Structure of the Order No.:		1	2	3	4	5	6	7	8	9	10	11	12	13	14	15

²⁾ No additional option must be specified in the order.

Determine themotor type according to cooling method, degree of protection and frame design (for further selection according to speed or number of poles, rated output, rated torque, rated speed and rated current, see the relevant "Preselection of the motor" tables)
