Direct drives

Direct drives are electrical machines that are directly connected to the working machine. The drive is designed so the gearbox can be omitted.

The direct drives from EAAT GmbH Chemnitz are ideal for highly dynamic motion processes and are designed based on the specifications of our customers. Together with measuring systems and frequency converters, we also ensure precise and even positioning of both rotating and linear direct drives. This creates many benefits.
