Downsizing with compact three-phase synchronous motors

Baumüller introduces the new DS4 motor generation

 At SPS – Smart Production Solutions, Baumüller will showcase its new DS4 motor generation. The three-phase synchronous motors were designed with a particular focus on compactness, yet they offer a wide speed range. 
The DS4 motors will initially be available in a liquid-cooled version in frame sizes 100 and 132; frame size 160 is in development. Additional lengths are available as an option, enabling downsizing compared to previous generations and thus reducing costs.
The DS4 motor generation consists of interior permanent magnet synchronous motors (IPMSM). This special manufacturing process, which uses embedded magnets, results in motors that are more powerful and more compact. Using less material also reduces inertia. As a result, the DS4 enables faster acceleration and deceleration and is suitable for dynamic applications such as textile machinery.
The DS4 models offer very high efficiency – up to 97% – across their entire operating range. This reduces operating costs for the machine operator through energy savings, particularly during continuous operation.

Thanks to their special manufacturing process, the new Baumüller three-phase synchronous motors achieve a particularly high power density, enabling downsizing and thus reducing costs.

Use in injection molding machines

Leading manufacturers of injection molding machines are already relying on the new DS4 motors. They were impressed not only by the motors’ compact design but also by their wide speed range, which is particularly advantageous for use with high-flow pumps that enable higher injection speeds and shorter cycle times. Baumüller’s DS4 motors are ideally suited for operating high-speed, high-flow pumps, thereby paving the way for increased productivity in injection molding machines.
