The SIMOTICS FD motor series has been specifically developed
for operation with SINAMICS converters. To supplement our
portfolio in the low-voltage motor range, a water-cooled version
for line operation has been created.
• The optimized efficiency results in lower operating costs.
• The high power density and compact design ensure low
space requirements combined with low weight.
• An optimally harmonized and coordinated drive system is
created as the motor is optimally matched to the converter. For
instance, it has optimized noise levels, the converter does not
have to be derated and the temperature rise is low.
• The cast-iron housing and bearing plates are extremely rigid
and rugged and can therefore be subject to high stress levels.
They have excellent vibration damping properties and are
resistant to corrosion.
• The bearings are designed for maximum reliability, which
results in good vibration characteristics, a long service life and
low maintenance costs.
• The DURIGNIT IR 2000 insulation system with VPI or current
UV impregnation results in high reliability, a long service life
and high resistance to stress, for example, during starting or
under overload conditions.
• Due to the low noise emission level, the stringent requirements
of occupational health and safety are fulfilled without the need
for any additional measures.
With SIMOTICS FD we have increased the power density so that
we offer higher power for the same frame size.
Optimally harmonized for converter operation
The new motor series has been optimized for operation with
SINAMICS G120P, G130, G150, S120, S120CM and S150
converters with regard to converter output currents and voltage
Through the use of optimized pulse patterns and the new nonribbed
enclosure, the SIMOTICS FD and converter system is
optimized from a noise perspective.
Higher degree of flexibility
As a result of the new motor design, SIMOTICS FD motors fulfill
the most exacting customer requirements in terms of variance
and mounted options. For instance, the optimized motor design
allows terminal boxes, separately-driven, external fans and
mounted coolers to be flexibly mounted as required and monitoring
devices can be added easily.
The optimized housing in a modern design has an attractive
appearance and enhances functionality as a result of the
flexible, modular system. For instance, this is ensured by the
optimized, easy to access terminal box that has been newly
developed, with flexible terminal box position.
Wider range of applications
The motors are available in country and sector-specific versions,
complying with the relevant regulations, standards and directives.
With their numerous options, the SIMOTICS FD motor series can
be used in all areas of industry. Paper, steel, energy, marine,
chemical, water/wastewater are just some examples of the
The available types of construction are IM B3, IM B35 and IM V1
according to EN 60034-7. IP55/IP54 is the standard degree of
protection (IP23 for open-circuit ventilation).
The wide field of applications that can be addressed includes,
for example, the following:
• Propeller drives, bow thrusters
• Paper machines
• Handling lines
• Conveyor belts
• Rolling mills
