Spare parts

10.1

Ordering data

When ordering spare parts, in addition to the precise designation of the spare part, specify the
motor type and the serial number of the motor. Ensure that the spare part designation matches
the designation in the spare part lists and add the associated part number.
Example
● Bearing shield, drive end (Part 5.00)
● Machine type 1LL1
● Serial number D21234567010001
The machine type and the serial number are indicated on the rating plate and in the technical
data, and are also embossed on the drive end of the shaft.
Note
The graphical representations in this chapter show schematic diagrams of the basic versions.
They are used for spare parts definitions. The supplied version may differ in details from these
representations.
You can use commercially available, standard components, but ensure that they have the
same construction type, dimensions, strength class etc.
10.2

Roller bearings

If roller-contact bearings with an insulated design are installed, use roller bearings of the same
type as spare parts. This will prevent any bearing damage being caused by bearing currents.
10.3

Anti-condensation heating

The anti-condensation heater is mounted directly on the winding. The anti-condensation heater
cannot be removed without causing damage to the winding. A new anti-condensation heater
may only be installed by Siemens Service Center (Page 155) specialists.
