SERVAX Direct Drives with integrated Ball Screw

Minimum processing times, pinpoint positioning, compact design and low installation expenditure are the benefits of direct drive technology, which is already very familiar to mechanical engineers. SERVAX Drives – a division of Landert Motoren AG – is now taking a giant leap forwards in terms of integration with its newly developed ball screw drive.

A 10 Nm direct drive is integrated in a housing with a capacity of only 1.6 liters in order to facilitate pinpoint positioning of a 600 kg milling head, for example. The synchronous motor can achieve 6 times its rated torque in order to accelerate or decelerate the load. To ensure maximum operational safety even in vertical applications, the developers at SERVAX have integrated an additional brake.

The milling head is guided by a ball screw, whose nuts are integrated in the motor, meaning that no additional bearings are required. The user thus obtains a connection with maximum rigidity (both static and dynamic) between the ball screw and the motor. As a result the acceleration capacity, positioning accuracy, uniformity of movement and application service life are all improved. It should also be borne in mind that when producing the machine there is no longer any need to spend time on installing the torque transmission by means of a toothed belt or other comparable equipment. Customized SERVAX drives result in product differentiation and excellent customer benefits.

Of course, the ball screw drive can also be rated for other applications.

SERVAX is again relying on its basic modular concept here. It can achieve maximum flexibility with minimum processing times because it has access to its own punching shop and the latest processing machines. The customer is present when electrical performance data is verified on the SERVAX test bench.
