7 reasons for direct drive technology

Productivity Although the focus in direct drive technology is generally on a high torque, the permanent-field synchronous motors offer good acceleration properties and are therefore suitable for dynamic processes with high output.

Compactness The high-pole direct drives of Baum��ller are an obvious choice due to their very high power density. In addition, the drive consists of just two parts, rotor and stator, and there are no transmission elements or hydraulic systems. The DST2 torque motors are also available as kit motors. This means that Baum��ller supplies the stator and the rotor only, without a housing and bearing, thereby enabling optimal integration in the machine.

Stiffness One of the most frequent reasons for the use of direct drives is the servo performance, which is significantly better than with motor-transmission combinations due to the stiffness of the connection between the motor and the load.

Life cycle costs The life cycle costs of the direct drives are influenced positively by two points: The energy efficiency is better compared to hydraulic solutions as well as the gear motor. The maintenance required is also significantly less compared to other solutions.

Low noise emissions Compared to hydraulic systems, direct drives are less noise-intensive; if the motors are also equipped with liquid cooling there are also no noise emissions from a fan.

Low maintenance and servicing work The direct drive system is almost oil-free, the motor has a very long life and is thus maintenance-free. The reduction in components produces less susceptibility to faults �C failures are avoided.

Energy efficiency As the direct drives have a high efficiency within the partial load range at constant speed and the friction losses are lower, the energy efficiency of the system is significantly better in comparison to gear motors. This drive type thus also runs efficiently when changing frequently between partial and nominal load. The second factor concerning the energy efficiency is the motor��s water cooling. The water cooling reduces not only the surface heat but also the heat input into the machine. This further increases the power density so that additional cost and energy-intensive fan cooling is no longer necessary.
