Water-cooled synchronous motor with 60.000 Nm torque

Baumüller offers many of his electric motors with water cooling. With a new one synchronous motor the drive specialist has now expanded its DST 2 series to include torques from 325 to 60.000 Nm. But also with all other electric motors Water Cooling the very compact design is more powerful than the fan-cooled motors.

With the new portfolio in the area of ​​water-cooled motors, water cooling is now available for almost the entire portfolio from Servomotor in size 45 to synchronous motors in size 560. Applications in the Food industry, Textile industry, Plastics processing or in forming and bending machines benefit from the compactness and performance of this water-cooled synchronous machine.

IE5 + synchronous motor for intralogistics and hygienic applications

The performance of the water-cooled is up to 50% higher than that of the uncooled drives. They can be made smaller and, thanks to their very good cooling properties, achieve greater dynamics.

Because the heat is dissipated directly at the motor, motors can be installed close together in the machine without the system overheating. So that falls Power Type much more compact out. Since the heat is dissipated in the machine, temperature-sensitive products can also be processed, as is required in the food industry.

Water-cooled engines are more environmentally friendly

With water-cooled motors, the dependency on Environmental conditions as the following examples show: As the ambient temperature rises, the effectiveness of the fan cooling decreases. Airborne contaminants foul the fans, which incur service costs to clean. On the other hand, water-cooled motors are optimally cooled even at high ambient temperatures.

Baumüller now offers a wide range of water-cooled motors with its complete range Scalability. Servomotors are available in sizes 45 to 132 with water cooling. Main drives are available from sizes 100 to 280. Synchronous motors are available in sizes 135 to 560 in water-cooled design.  

Water-cooled electric motors: compact, powerful, quiet

The servomotors 45 and 56 have water cooling directly in the motor housing built in and do without an additional coating. This means that the water-cooled servomotors are just as big as the uncooled variants. The higher performance is therefore not at the expense of compactness.

The engine can be cooled in addition to water also with oil respectively. Servohydraulic systems that already have oil available in the machine can also be operated with it.

Water-cooled synchronous motor with 60.000 Nm torque

With the new synchronous motor Size 560 of the DST2 torque motors used for? Baumüller its electrical direct drive technology accessible for new areas of application. Maintenance intensive Transmission, lossy standard motors or conventional hydraulic systems now no longer have a chance of driving up the life cycle costs.

Manufacturers of presses, shredders, extruders and shipbuilders are using it more and more often Direct Drives. Because the electric motors are largely maintenance-free compared to conventional drive systems. This increases the field of possible applications for such drives.

The torque motors of the DST2 series are permanent magnet, multi-pole synchronous motors with water cooling. Baumüller has now expanded the sizes 135 to 400 by the new size 560. This covers a range from 325 to 60.000 Nm at maximum torque. The compact synchronous motors have a particularly high torque density at low and medium speeds. They are particularly suitable for use as direct drives. The synchronous motors also offer a high overload capacity and very good concentricity properties.

 Universal motor in 20 variants for worldwide use

With the torque motors, a patented Integrated stainless steel water cooling for optimal dissipation of heat losses with a high degree of protection. A fan unit to cool the motor is not required, the noise emissions remain low. There are various shafts and flanges for integration in the machine.

Synchronous motor and converter result in servo drive

In combination of high-torque motors with the inverters the series B maxx 5500 Baumüller offers suitable servo drives. The high-performance mono units have integrated rectifiers, intermediate circuit capacitors and inverters. The frequency converter are available with different cooling systems.

When operating the DST2 560, several frequency converters can run on one motor. Thanks to an integrated function in the servo drive, multi-wound motors can be operated without splitting the encoder cable. Here he communicates fieldbus the encoder actual values. The number of Multiple windings is not limited and an additional wiring is not needed. Various encoder systems such as resolvers or absolute value encoders can be used.

Redundant winding for more safety

Safety in case of damage on the insulation system offers an additional option. With a redundant winding system, the motor can then continue to be operated with reduced power. This avoids a costly complete failure.

IE5 + synchronous motor for variant reduction and TCO reduction

With the combined Motor-converter drive Baumüller offers a powerful, scalable system for applications in the higher performance range. The simulation software Pro simulation. It can significantly shorten the development time for machines and systems with synchronous motors from Baumüller. The motor's force and movement curves can be tested very easily on the PC, and commissioning is simulated virtually.
