Direct drive technology for innovative machine solutions

The torque motors in the DST2 series are permanent- noise emission from the motor. The robust and
magnet multi-pole synchronous motors in water- compact motors are also largely maintenance-free,
cooled design. Because of the high torque densities which is another plus for economical operation.
in the low and medium speed range, the energy-
efficient motor series is particularly suitable for the
direct drive in general mechanical engineering.
In combination with the high overload capability
and the very good smooth running characteristics
of the drives, sophisticated and dynamic applica-
tions can be implemented.

The integrated water cooling with stainless steel

allows optimal dissipation of losses with a high
protection level. A fan unit is not necessary with
these motors, which means significantly reduced

brand four-shaft shredder

Baumüller set the standard in the early 90s with the introduction of direct drive technology for printing
machines. With direct drives, we now offer the most technologically and economically advanced solution
on the market for the recycling industry as well, in particular for shredders. Our torque motors can power
the wheels of the grinders either directly or through internal gears – both solutions are well established
on the market.

Higher product quality and productivity

• Different movement profiles depending
on the material
• Steering of the drives controlled by torque (tor-
que distribution) for mechanically coupled motors
with the required precision and dynamics
• Very smooth running characteristics with
load balancing

Many market leaders rely on Baumüller high-torque motors with an integrated pressure bearing to
power an extrusion screw. This optimally satisfies the requirements of extrusion technology and offers
numerous advantages to the machine maker.

Lower operating costs

• No transmission losses
• No service on the transmission
• Greater machine density and thus less use
of production area
• Higher overall effectiveness, especially with
high material mix and operation at partial load
• High precisions for extruders and chill-roll

 Schiffe
Ships

With a hybrid drive, the ship’s propellers are powered electrically by converter-fed synchronous motors
which receive their energy from battery and diesel generators, e.g. LNG, diesel, fuel cells, etc.
Many benefits make the combination of combustion motor and electric motor particularly attractive for
shipping. Along with a significant reduction in fuel consumption in moving bodies of water, this system
also reduces noise and vibrations by up to 28 percent.

DST2 — Powerful motors

The high-torque motors DST2 are certified by the

Lloyd’s Register and meet the specific requirements
for shipping. The water-cooled direct drives are
constructed with protection class IP 54, are not
susceptible to dirt accumulation and run with low
noise. With their compact and robust construction,
the motors take up minimal space in the engine
room and are well suited for rough conditions on
the water. Powerful direct drive technology with
up to 60,000 Nm improves the performance of the
ship drive and positively affects the reverse thrust
and bollard pull.
