AL8121-0Eyz-0000 | Linear servomotor, 100 N (F_max), convection

The AL8121 linear servomotor is suitable for highly dynamic and powerful linear axes operating on 48 V DC and has a pole pair distance of 24 mm. The optimized product design and modular coil concept allow for maximum force density within a minimal footprint. The overall length of the primary part is 93 mm. The AL8121 reaches a maximum speed of 2.5 to 4.5 m/s with a peak force F_max of 100 N. Cooling is achieved via convection.

Symmetrical and flexible motor design

The AL8100 linear motors feature a symmetrical drilling pattern that simplifies the design and allows for a universal machine configuration. In addition, critical hotspots are avoided by allowing for even contact between the linear motor and the machine carriage.

High force density

The modular coil concept allows for a flexible and highly compact design of the linear motor. Despite this compact design, the space-saving linear motors in the AL8100 series feature high peak forces and thus provide optimum force density.

Made in Germany

Both the development and the production of the AL8100 take place in Germany. With its long-standing experience in drive technology, Beckhoff guarantees a high level of product quality for durable and reliable applications.

One Cable Technology

The primary parts can be optionally equipped with One Cable Techonolgy (OCT). In this setup, the scanning head of the linear encoder forms a unit together with the primary part, both mechanically and electrically. This means that only one cable is required for the power supply, feedback system, and thermal sensor. In addition to the reduced cabling effort and the associated faster electrical installation, commissioning is also simplified by an online assessment rating of the encoder’s signal quality and the electronic nameplate. When connected to the ELM72xx servo terminals, all relevant motor parameters are read out directly. What’s more, the mechanical assembly of the scanning head is not required, since this is achieved by installing the primary part.

The complete system requires additional components, such as the scale tape and the rail for simplified installation of the scale tape.
