Synchronous linear servomotors (SL2)

SL2 motors save time during project planning

Precise, reliable and safe at any speed

Virtually maintenance-free

SL2 series

The already high demands on machine cycles, acceleration and linear travel speeds for drive systems in handling, transportation and production continue to increase steadily. Whether as highly dynamic and flexible processing machines for handling or in pick-and-place applications, the new SL2 synchronous linear motors by SEW-EURODRIVE are the ideal solution for such requirements. As linear motion and force is generated directly, no mechanical transmission elements subject to wear, such as spindles, ball bearings or toothed belts, are required. An optimum force-density ratio is achieved by using the latest winding technology and a laminated iron core. The SL2 synchronous linear motor with convection cooling is practically maintenance-free and offers maximum reliability and availability, high control quality, speed and accuracy.

SL2 synchronous linear motors are available in three designs for speed classes 1, 3 and 6 m/s (3, 10 and 20 ft/s): SL2 Basic, SL2 Advance System and SL2 Power System. For longer travel distances, secondaries are available in different lengths and can be easily lined up with one another. The SL2 Advance System features a motor cooling unit, which provides even better cooling than SL2 Basic. A forced-air cooling fan gives the SL2 Power System a further power boost.

Accessories and options for linear servomotors

AL1H length measuring system

SEW-EURODRIVE can equip the SL2 Advance System and SL2 Power System linear servomotors with the AL1H absolute length measuring system. AL1H consists of a linear sensor, which is attached to the motor cooling unit along with the encoder components, and a measuring tape, which is routed along the travel section. The AL1H length measuring system is dirt-resistant and permits high speeds and acceleration. Encoder components that are ready for use facilitate fast, simple and cost-effective mounting of the AL1H.

Pre-fabricated cables for linear servomotors

SEW-EURODRIVE offers optional pre-fabricated power and feedback cables for SL2 Advance System and SL2 Power System linear servomotors, enabling straightforward and reliable connection.

Power cables are fitted with the appropriate plug connector on the motor side. The shield is connected in the connector housing according to EMC requirements. All plug connectors seal the plug on the cable end with a lamellar seal and ensure strain relief in accordance with EN 61884. On the inverter side, the single conductors are exposed, and the shield is ready for connection in the control cabinet. The parts included allow you to customize the single conductors specifically for your inverter.

The encoder end of the feedback cable is ready for connection to the AL1H length measuring system. A commercial sub-D EMC connector with pin contacts is used on the inverter end. A 9-pin or 15-pin plug is used, depending on the inverter used.
