long operating life, and provides a maintenance alarm signal.
Electrical input is nominally rated as three-phase, lowvoltage
a.c. 400 V (with an allowable input voltage range
of 380-480 V a.c.), and the VFDs come in 14 models with
a capacity range of up to 139 A. Each VFD is quadruple
rated for varying duties - normal or heavy overload, and
mild (40°C) or high (50°C) temperatures - so users can
minimize the number of models needed to handle a wide
range of applications. Other functionality includes control
of mechanical brakes, a built-in braking transistor, regeneration
avoidance and low-voltage ride through. Safe torque
off (STO) capability ensures the VFD fulfills functional safety
standard requirements while eliminating the need for external
circuit breakers required by conventional VFDs. -

Severe-duty a.c. motors with 75-800-hp output
The Simotics SD200 severe-duty motor in frame size 440
(photo) provides high productivity and energy-efficient operation
in all torque
ranges. These new
cast-iron NEMA
motors are built
to power pumps,
fans, compressors,
hoists, winders and
similar equipment
in harsh environments.
With a three-year warranty, the SD200 motors
offer 75-800-hp output and feature 444-5013 cast-iron
frames for operation in 460 and 575 V ranges. They meet
or exceed NEMA Premium MG1 Table 12-12 efficiencies.
A wide selection of options is offered, including IP56 ingress
protection, encoders, brakes and blowers, plus
others to suit the applications presented. On these motors,
the frame, end-shields, fan guard and easy-access,
diagonally split, oversized terminal box are all cast-iron.
Complementing this construction are zinc-plated hardware,
epoxy paint and stainless-steel nameplates for long
life and easy identification in the field. A unique offset rotor
bar provides improved efficiency, while larger bars and end
rings reduce resistance. Each die-cast aluminum rotor assembly
is dynamically balanced for extended bearing life
and includes a high-strength C1045 carbon-steel shaft for
maximum performance. - Siemens USA, St. Paul, Minn.

Silver Sustainability Certificate for this company
This company was assessed by the global sustainability
rating agency EcoVadis in 2022 and awarded the silver
sustainability certificate (photo, p. 20). The company received
65 out of 100 points, placing them in the 89th percentile
rank and significantly higher than the average ratings
scored by other companies in the industry. The company's
latest innovations include the highly efficient IE5+ product
line, consisting of the DuoDrive integrated gear unit and
motor, IE5+ synchronous motors, and Nordac ON/ON+
variable-frequency drives. This series not only offers high
efficiencies, but also works to reduce the number of system
variants and total cost of ownership. - Getriebebau Nord
GmbH & Co. KG, Bargteheide, Germany
