Technical definitions for servomotors
General information
7
■
Overview
The servomotors deployed in SIMOTICS S-1FG1 servo geared
motors are extremely compact, permanent-magnet-excited
synchronous motors. With the available options and encoders,
the servomotors can be combined with gearboxes to create the
ideal solution for virtually any application. They therefore also
satisfy the permanently increasing demands of state-of-the-art
machine generations.
SIMOTICS S-1FG1 servo geared motors can be combined with
the SINAMICS S120 drive system to create a powerful system
with high functionality. The integrated encoder systems for
speed and position control can be selected depending on the
application.
The motors are designed for operation without external cooling
and the heat is dissipated through the motor surface and via the
flange connection to the gearbox. The servo geared motors
have a high overload capability.
The motors are coded in the 9th to 13th positions of the
Article No.
Ordering example:
As this example demonstrates, the motor is characterized by the
following features within the Article No.:
•
Motor encoder:
See next page for further information
•
Motor shaft height and motor length:
See overview table on page 7/4
•
Rated motor speed:
The rated motor speed should be regarded as an informative
value. The rated motor speed does not necessarily reflect the
speed that can be input to the gearbox. The maximum permis-
sible short-time speed at the gearbox input
n
1max
and the
maximum permissible (short-time) output torques
M
2max
can
be found in the "Technical specifications" of the relevant chap-
ters for selection of servo geared motors.
•
Motor type:
Motors can be ordered in versions Compact (CT) and High
Dynamic (HD).
The motors in the Compact class are characterized by their
compact dimensions and very high power density. The
motors in the High Dynamic class have an excellent dynamic
response thanks to their very low moment of inertia.
•
DC link voltage:
The motors are designed for various DC link voltages ranging
from 510 V to 720 V or 270 V to 360 V.
