■ Overview
The 1LE and 1FP motors (with the exception of 1LE1 with option
F90 – version "Forced-air cooled motors without external fan and
fan cover" and 1PC1) can be used in a much wider range of applications
(e.g. as motors with brakes) if the following modules
are mounted:
• Separately driven fan
• Brake
• Rotary pulse encoder
Separately driven fan
The use of a separately driven fan is recommended to increase
motor utilization at low speeds and to limit noise generation at
speeds significantly higher than the synchronous speed. Both of
these results can only be achieved with converter operation.
Please inquire about traction and vibratory operation.
The separately driven fan can be supplied already fitted, order
code F70. There is no automatic adjustment of the voltage for the
separately driven fan when ordering a "special voltage" for the
motor. This must be specified in addition using the Y81 option.
It can also be ordered separately and retrofitted. For selection information
and article numbers, see the section "Accessories"

Introduction
Mounting technology
Modular technology
The brake must always be mounted in the factory for safety reasons.
The rotary pulse encoder and/or the separately driven fan
can also be retrofitted.
The degree of protection of the motors with modular technology
is IP55. Higher degrees of protection on request.
Attaching rotary pulse encoder, brake, and separately driven fan
increases the length of the motor by dimension l. For explanations
of the additional dimension and weights, see "Mounting
technology" and "Dimensions and weights" from page 1/104.
(available soon). A rating plate listing all the important data is
fitted to the separately driven fan. Please note the direction of rotation
of the separately driven fan (axial-flow fan) when connecting
it. Admissible coolant temperatures CT min –25 °C, CT max
+65 °C 1) , for frame sizes 400 and 450 coolant temperatures
CT min –20 °C, CT max +40 °C, lower/higher coolant temperatures
are available on request.
When the separately driven fan is mounted, the length of the motor
increases by l. For explanations of the additional dimension
and weights, see "Mounting technology" and "Dimensions and
weights" from page 1/104.
