Overview
The core elements of a fully integrated drive system are fre-
quency converters/inverters, motors, couplings and gear units.
Siemens offers all the required components in top manufacturing
quality from a single source, perfectly integrated – operating
perfectly together, for all performance classes.
As a standard solution or tailored to individual requirements: no
other provider on the market is able to offer a comparable port-
folio. All Siemens drive components are optimally tuned to each
other so that they interact ideally in every application.
Siemens Integrated Drive Systems turn simple drive compo-
nents into real systems. Drive technology based on IDS ensures
maximum productivity, energy efficiency and reliability in every
automation environment and over the entire product lifecycle.
SINAMICS G120P frequency converters
SINAMICS G120P is an important element of an integrated drive
system. The core elements of a fully integrated drive system are
SINAMICS G120P frequency converters, motor types
SIMOTICS SD and GP (VSD10 Line) and SIMOTICS FD, as well
as couplings. Vertical integration is achieved by the CU230P-2
Control Unit.
Drives with a quadratic load torque (M~n
2
), such as drives for
pumps and fans, require the full torque at rated speed. Gener-
ally, increased starting torques or load surges do not occur.
The following applies to selection of a suitable converter for
drives with a quadratic load torque: The rated current of the con-
verter must be at least as large as the motor current at full torque
in the required load point.
SIMOTICS GP and SIMOTICS SD – VSD10 Line motors
VSD10 Line motors are based on the 1LE1 platform and are
available in the following versions:
•
General Purpose Motors, shaft heights from 100 to 160,
aluminum
•
Severe Duty Motors, shaft heights from 100 to 315, cast iron
These motors are optimized for operation on a SINAMICS G120
converter. They are intended solely for converter operation.
They must not be connected directly to a mains supply.
Functions integrated as standard for converter operation:
•
Insulation system optimized for converter operation
•
Built-in temperature sensor
•
Bearing insulation NDE (shaft height 280/315)
The VSD10 Line provides the link to the SIMOTICS FD series for
converter-fed motors.
SIMOTICS FD motors
The new generation of SIMOTICS FD (Flexible Duty) low-voltage
motors will be available in four shaft heights with output ratings
ranging from 200 kW to 1600 kW and higher. SIMOTICS FD
motors are based on an innovative modular system. These air-
cooled and water-cooled converter motors are available in
numerous different versions and therefore suitable for a wide
variety of applications in a host of different industries.
SIMOTICS FD in shaft heights 315 to 400 is designed for opera-
tion on SINAMICS G120P converters with output ratings ranging
from 200 kW to 630 kW.
FLENDER couplings as part of the drive system
A drive system comprises individual machines, including the
motor and gear unit. Couplings combine these components and
frequently also establish the connection to the driven machine.
The coupling can perform other tasks in addition to the transmis-
sion of rotary motion and torque, such as:
•
Compensation for
shaft misalignment
with low restorative
forces
•
Influencing of intrinsic torsional frequency and
damping
•
Torque interruption or limitation in response to
overload
• Electrical
insulation
, noise insulation
•
Function in
explosive environments
